To prove triangle JKL is a right triangle, we must show that Choose... is a right angle
Since triangle DEF is given to be right triangle, the Pythagorean theorem can be applied to
determine that Choose...
We already know that a + b = c in triangle JKL, so
these two equations show that Choose...
which is enough to
prove that triangles DEF and JKL are congruent triangles. Then, triangle JKL must be a
