Diagonal Calculation
Pythagoras' Theorem tells that:
The square of the hypotenuse is equal to the sum of the squares of the two shorter sides.

a +b =c 2
Here, a = Perpendicular
b = Base
c = Diagonal
Example: Find the diagonal of the triangle given below, using Pythagoras' Theorem
Here,
a = 5m b = 12m c =?
Since,

a +b =c

c =169
c=√169
C=13m
