Shape geometry: Square
For a square, all four sides are the same length.
If you draw a diagonal line from the lower left corner to the upper right corner, you'll have 2 right triangles.
The diagonal line is called the hypothenuse of a right triangle.
The formula to calculate the length of diagonal (Hypothenuse) is called the Pythagorean Theorem:
a^2 + b^2= c^2
a= height of triangle
b= base of triangle
c= diagonal/hypotenuse of of triangle
Solution:
a=15cm
b=15cm
Find c:
15^2+15^2 = c^2
c=sqrt(15^2+15^2)
