In geometry, a diagonal is a line segment joining two vertices of a polygon or polyhedron, when those vertices are not on the same edge. Informally, any sloping line is called diagonal.

Correspondingly, what is a diagonal and example?

The definition of diagonal is something with slanted lines or a line that connects one corner with the corner furthest away. An example of diagonal is a line going from the bottom left corner of a square to the top right corner. YourDictionary definition and usage example.

Beside above, what is a diagonal line look like? Diagonal is a kind of straight line. A diagonal line does not go straight up, down, or across. For example, in geometry a diagonal is any line that goes between the corners of a polygon. So a square has two diagonals, and a five-sided shape has five diagonals.

Similarly, you may ask, what is the meaning of diagonal lines?

A diagonal is made out of a straight line that's set at an angle instead of straight up or across. If you picture a square and draw a line connecting the opposite corners, that's a diagonal line. You'll find diagonal lines in geometry, and also in the world around you. Diagonal can be either a noun or an adjective.

How do you know it is a diagonal segment?

A diagonal of a polygon is a line segment joining two vertices. From any given vertex, there is no diagonal to the vertex on either side of it, since that would lay on top of a side. Also, there is obviously no diagonal from a vertex back to itself. This means there are three less diagonals than there are vertices. Professional

## How do you find the diagonal?

What is the diagonal measurement of a rectangle 150 feet in length by 100 feet in width? Use the Pythagorean Theorem (a^2 + b^2 = c^2). A and B are the lengths of the two sides of the rectangle. To get the length of the hypotenuse, you would need to solve for C. C is the square root of (A squared plus B squared). Professional

## What's a diagonal line?

Diagonal. more A line segment that goes from one corner to another, but is not an edge. So when we directly join any two corners (called "vertices") which are not already joined by an edge, we get a diagonal. Diagonals of Polygons. Professional

## What are diagonals of a quadrilateral?

A quadrilateral is a closed plane figure bounded by four line segments. For example, the figure ABCD shown here is a quadrilateral. A line segment drawn from one vertex of a quadrilateral to the opposite vertex is called a diagonal of the quadrilateral. For example, AC is a diagonal of quadrilateral ABCD, and so is BD. Explainer

## What is a diagonal position?

A Diagonal line is a line from a Place on one Side line of a Longwise set to a Place one or more Places Up or Down on the Opposite Side. The line joining the First corner positions is called the First corners' Diagonal and the line joining the Second corner positions is called the Second corners' Diagonal. Explainer

## How do you find the diagonal of a shape?

The number of diagonals in a polygon that can be drawn from any vertex in a polygon is three less than the number of sides. To find the total number of diagonals in a polygon, multiply the number of diagonals per vertex (n - 3) by the number of vertices, n, and divide by 2 (otherwise each diagonal is counted twice). Explainer

## How do you find area?

The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area. Pundit

## What does it mean to be congruent?

Congruent. Angles are congruent when they are the same size (in degrees or radians). Sides are congruent when they are the same length. Pundit

## What does cut on the diagonal mean?

Cutting Vegetables on the Diagonal
You may have noticed that many Chinese recipes call for vegetables to be cut "on the diagonal." Diagonal cutting is a simple Chinese cooking technique that can be used with many vegetables. Cutting vegetables on the diagonal exposes more of the vegetable's surface area to the heat. Pundit

## What is the opposite of diagonal?

What is the opposite of diagonal?
even level
straight forthright
straightforward upright Pundit

## What is the meaning of vertical line?

Vertical line (Coordinate Geometry) Definition: A line on the coordinate plane where all points on the line have the same x-coordinate. Try this Drag the points A or B and note the line is vertical when they both have the same x-coordinate. Pundit

## How do diagonal lines make you feel?

Diagonal lines suggest a feeling of movement or direction. Since objects in a diagonal position are unstable in relation to gravity, being neither vertical nor horizontal, they are either about to fall, or are already in motion, as is certainly the case for this group of dancers. Teacher

## What are the five basic types of lines?

There are five basic kinds of lines: vertical, horizontal, diagonal, curved, and zigzag. Vertical lines (Figure 4.7) move straight up and down—they do not lean at all. Teacher

## What is the slope of a diagonal line?

Lines that fall from left to right have a negative slope. So a diagonal line to the right ( / ) would have a positive slope. A diagonal line to the left ( ) would have a negative slope. A vertical line ( | )has an undefined slope and a horizontal line ( ---- ) has a slope of 0. Teacher

## What is a perpendicular line?

In elementary geometry, the property of being perpendicular (perpendicularity) is the relationship between two lines which meet at a right angle (90 degrees). A line is said to be perpendicular to another line if the two lines intersect at a right angle. Teacher

## What does a horizontal line look like?

A horizontal line is one which runs left-to-right across the page. In geometry, a horizontal line is one which runs from left to right across the page. It comes from the word 'horizon', in the sense that horizontal lines are parallel to the horizon. Its cousin is the vertical line which runs up and down the page. Reviewer

## What is the use of diagonal scale?

Diagonal scale is an engineering measuring instrument which is composed of a set of parallel straight lines which are obliquely crossed by another set of straight lines. Diagonal scales are used to measure small fractions of the unit of measurement. Reviewer

## What is a straight line called?

A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is sometimes called a straight line or, more archaically, a right line (Casey 1893), to emphasize that it has no "wiggles" anywhere along its length. Reviewer

## Is straight line a curve?

A curve is not a straight line, just as a straight line is not a curve. A curved line contains points that are not linear to two given points. The curve moves in other directions from the straight line created by joining collinear points. Reviewer

## How do I find the diagonal of a rectangle?

To find the diagonal of a rectangle formula, you can divide a rectangle into two congruent right triangles, i.e., triangles with one angle of 90°. Each triangle will have sides of length l and w and a hypotenuse of length d . Co-Authored By:
