Answer:
If we know the lengths of two sides of a right angled triangle, we can find the length of the third side. ... Then we use algebra to find any missing value
Explanation:
(Hypotenuse)2 = (Shortest side)2 + (Other side)2
so
(Longest side)2 = (Shortest side)2 + (Other side) 2
To find the length of the hypotenuse
1. Sketch triangle and mark hypotenuse
2. Write out Pythagoras' theorem for the triangle
(Hypotenuse)2 = (Shortest side) 2 + (Other side) 2
3. Solve
4. Write out solution
1a. Reverse this for a or b through subtraction;
So that b ² = c ² - a² or a² = c² - b²
