Questions & Answers

How do I use Pythagoras' Theorem to calculate the hypotenuse of a triangle?

Adjacent^2 +Perpendicular^2 = Hypotenuse ^2

Example:


Adjacent = 4cm

Perpendicular = 6cm

Adjacent^2 = (4)^2 = 16cm

Perpendicular^2 = (6)^2 = 36cm

Hypotenuse^2 = 16 + 36 

Hypotenuse^2 = 52

Hypotenuse = sqrt (52) = 2 sqrt(13)cm
