Pythagorean theorem: #a^2+b^2=c^2#

This only applies to right angle triangles (one of the angles is #90^@#s)

If you want to find the length of a triangle where it's A=3 B=4 C=?

you do #3^2+4^2=?#

#9+16= 25#

and

#5^2=25#

Therefore

C=5

you can also use it to find A or B by doing #C^2-A^2=B^2# or #C^2-B^2=A^2#
