What is a rigid shape?
rigid. • a shape that can’t be pushed to make a different shape. • a triangle is the only rigid polygon, so triangles are often used.
Which shape is considered the most rigid shape?
Triangles are used in structures because they are the most rigid shape.
How many diagonals does a shape have?
Answer. 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)….Solved Examples.

What is the number of diagonals in a polygon?
A diagonal is a segment that connects two non-consecutive vertices in a polygon. 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.
How to find the number of diagonals in an octagon?
A octagon has 20 diagonals. Define the formula. The formula to find the number of diagonals of a polygon is n (n-3)/2 where “n” equals the number of sides of the polygon. 
The diagonals of a square are the line segments that link opposite vertices of the square. A square has two diagonals. The two diagonals of the square are congruent to each other. It bisects each other and divides each diagonal into two equal parts.
How many diagonals does a quadrilateral have?
A quadrilateral, the next-simplest, has two diagonals. A pentagon, whether regular or irregular, has five diagonals. In convex, simple polygons, diagonals will always be within the interior. Consider a rectangular door.
