How can you find the side of a triangle with its base length

If the length of bb is unknown, using the pythagorean theorem, then knowing a/2 a/2 and hh will allow you to solve for bb.

Knowing bb and hh will allow you to solve for a2 a2 by the pythagorean theorem Then double the value of a/2 a/2 to get aa.

Is it a right triangle? If so use the Pythagorean theorem (a2+b2=c2)
