Question from Katie, a student:

How do I find the side lengths of a triangle knowing the base and its height?

Thank you,

Hi Katie,

You don't. Here are two triangles with the same base and height but with sides of quite different lengths.


If however the triangle is isosceles as is the case with the triangle on the right then you can use Pythagoras Theorem to find the lengths of the other two sides.
