What is Pythagoras Theorem?
According to Pythagoras Theorem, in a right angled triangle the square of the side opposite to the right angle is equal to the sum of squares of the other two sides.
Height² + Base² = Hypotenuse²
The right triangle has base of 4 units and hypotenuse of 12 units,
Height is represented by x units.
By Pythagoras theorem,
x² + 4² = 12²
x² = 144 -16
x² = 128
x = 11.31 units
