Find the area of the right triangle with hypotenuse length 17cm and one leg length 15cm Don't tell me the answer instead the formula thanks  January 20th, 2017, 06:53 PM #2 Member   Joined: Oct 2016 From: Melbourne Posts: 77 Thanks: 35 If you have a right angle triangle, the three sides are related by Pythagoras' Theorem: \displaystyle \begin{align*} a^2 + b^2 = c^2 \end{align*} (note that c is always the Hypotenuse). That means that if you have any two sides, you can use Pythagoras' Theorem to find the third. Thanks from ghira001 January 21st, 2017, 03:57 PM   #3
