What is a diagonal in geometry?
A more general definition of a diagonal of a polygon is a line segment that joins two vertices of the polygon which are not already joined by an edge of the polygon.
What is diagonal in simple words?
A diagonal is a line segment connecting the opposite vertices (or corners) of a polygon. In other words, a diagonal is a line segment connecting two non-adjacent vertices of a polygon. It joins the vertices of a polygon, excluding the edges of the figure.
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.
What is diagonal for kids?
A diagonal is a straight line joining two nonadjacent vertices of a shape, that is, two corners of a shape that are not next to each other.
What is a diagonal line called?
“a diagonal line across the page” Synonyms: oblique. slanting or inclined in direction or course or position–neither parallel nor perpendicular nor right-angled. (geometry) a straight line connecting any two vertices of a polygon that are not adjacent. type of: straight line.
Which way is diagonal?
A diagonal line or movement goes in a sloping direction, for example, from one corner of a square across to the opposite corner.
What is the difference between diagonal and horizontal?
Horizontal lines go from left to right across the page. Vertical lines go straight up and down. Diagonal lines are set at an angle. Inside a shape, a diagonal line goes from one corner to another.
What is diagonal of a polygon?
In a polygon, the diagonal is the line segment that joins two non-adjacent vertices. An interesting fact about the diagonals of a polygon is that in concave polygons, at least one diagonal is actually outside the polygon.
What is diagonal and vertical?
Vertical: In an up-down position, upright. Diagonal: In a slanted direction.
What is the difference between diagonal and vertical?
Vertical lines go straight up and down. Diagonal lines are set at an angle. Inside a shape, a diagonal line goes from one corner to another.

What is a diagonal direction?
adjective. A diagonal line or movement goes in a sloping direction, for example, from one corner of a square across to the opposite corner.
What is diagonal and horizontal?
Horizontal: Going side-to-side, like the horizon. Vertical: In an up-down position, upright. Diagonal: In a slanted direction.
Is diagonal straight across?
Diagonal is a kind of straight line. A diagonal line does not go straight up, down, or across. It is a line that connects two corners of a shape.
What type of line is diagonal?
Diagonal lines are straight lines that slant in any direction except horizontal or vertical. When in use, they suggest movement or lack of stability. Zigzag lines are a series of diagonal lines joined at ends. They can convey action and excitement, as well as restlessness and anxiety.
Which direction is diagonally?
Meaning of diagonally in English. in a straight and sloping way that is not horizontal or vertical, for example joining two opposite corners of a square or other flat shape with four sides: It’s quickest if you cut diagonally across the park.
What is the diagonal of a triangle?
A triangle has no diagonals. We know that a diagonal always connects any two non-adjacent (non-consecutive) vertices of a polygon. Since all the vertices of a triangle are connected by sides, no diagonals can be formed.
Is diagonal straight?
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.
What’s the formula of diagonal?
Number of Diagonals = n(n-3)/2
In other words, an n-sided polygon has n-vertices which can be joined with each other in nC2 ways. Now by subtracting n with nC2 ways, the formula obtained is n(n-3)/2. For example, in a hexagon, the total sides are 6.

What is the diagonal formula?
In other words, an n-sided polygon has n-vertices which can be joined with each other in nC2 ways. Now by subtracting n with nC2 ways, the formula obtained is n(n-3)/2. For example, in a hexagon, the total sides are 6. So, the total diagonals will be 6(6-3)/2 = 9.
What is diagonal of a square?
To calculate the diagonal of a square, multiply the length of the side by the square root of 2: d = a√2. So, for example, if the square side is equal to 5 in, then the diagonal is 5√2 in ≈ 7.071 in.
