Question

When i am solving for the sides of a right triangle, when will i use pythagorean theorem

Answer 1

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

Step-by-step 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

Example attached for you.

Answer 2

Answer:

When you are given 2 sides to find the other side or given 3 sides to say if it is a triplet
