How do you do a Pythagorean theorem?

Answer 1

The Pythagorean theorem can be done this way.

a²+b²=c²

lets say that you have a triangle with three sides, but you are only given two. Their values are 3 and 4. Now you have to fill in the values with a=3 and b=4 (doesn't matter which order you put it in)

3²+4²=c²

c is still unknown so we have to do the next step.

3² is 9 and 4² is 16. knowing this, we have to do this next:

9+16=c²

9+16 is 25.

25=c²

now you must get rid of the ². you do this by using the square root.

don't ask me why you square root, that's just how the Pythagorean theorem works.

√25=√c²

the square root gets rid of the c squared so its just the square root of 25.

5=c

triangle sides: 3,4,5

The process can also be reversed.

a²=c²-b²

or

b²=c²-a²
