## Are the diagonals of any regular polygon congruent?

In some regular polygons, the center of polygon is intersection of diagonals. … These triangles are called characteristic triangles of regular polygon. These tringles are congruent. Since this is a regular polygon, all sides have equal lengths and interior angles have equal measures.

## Are pentagons always congruent?

So, the sum of the interior angles of a pentagon is 540 degrees. All sides are the same length (congruent) and all interior angles are the same size (congruent).

## Do all pentagons have 5 congruent sides?

A regular pentagon must have five congruent sides, five congruent interior angles, and congruent exterior angles: five congruent sides (sides of equal length) five congruent interior angles (each measuring 108° )

## Do diagonals of a pentagon bisect each other?

If you take the meaning of bisect to mean a division into two equal halves, then a simple counterexample disproves this notion: none of the diagonals of a regular pentagon bisect each other so the answer is a definite no.

## What are the diagonals of a regular pentagon?

For regular pentagon number of sides = 5. Hence, the number of diagonals of a regular pentagon is 5, which is also visible from the above figure.

## What is the difference between a pentagon and a regular pentagon?

All pentagons have five straight sides, but the sides do not have to be of equal length. A regular pentagon has five equal sides and five equal angles. In basic geometry, most problems will involve regular polygons. … If the five sides of a shape are NOT connected or the shape has a curved side(s), it is NOT a pentagon.

## Can a regular polygon be a pentagon?

A pentagon is a polygon with five sides and five angles and can be either a regular or irregular polygon, depending on the measurements of its sides and angles.

## How many diagonals does a pentagon have *?

5 diagonals
Thus, a regular pentagon has 5 diagonals.

## How do you find the diagonals of a pentagon?

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). 4.

Solved Examples.
Polygon Name Number of Sides Number of Diagonals
Pentagon 5 5
Hexagon 6 9
Heptagon 7 14

## How many diagonals does a regular pentagon have class 8?

Final solution: Hence, with the help of formula (A) as mentioned in the solution hint we have obtained the number of diagonals in a regular pentagon which are 5.

## Which of the following is always a regular polygon *?

A square is a polygon that is always regular. By definition, a square has four equal sides, so it is equilateral.

## Which polygon is a regular polygon?

Any polygon that is both equilateral and equiangular is a regular polygon (e.g., equilateral triangle, square).
