## What is a diagonal of a rectangle?

Diagonals are the line segments that connect two non-adjacent vertices of polygons. Rectangles have two diagonals that connect two opposite vertices. They are the same size. In this activity, we will count the number of squares the diagonal passes through.

What is the equation for finding diagonals?

The formula for calculating the number of diagonals is: diag = n*(n – 3)/2. where “diag” is the number of diagonals, and n is the number of vertices (remember, the number of vertices of a polygon is the same as the number of sides).

What is the definition of diagonal lines?

A diagonal is a line segment that links two vertices of a polygon that are not adjacent. In a polygon with n sides (an “n-gon”) the number of diagonals is.
