Question

The following uses a 4-step proof, starting with the given statement. Complete the following proof

Answer 1

1) $\overline{JK} \perp \overline{MN}$

2) $\angle JKM$ is a right angle (perpendicular lines form right angles)

3) $\triangle JKM$ is a right triangle (definition of a right triangle)

4) $\angle 1$ and $\angle 2$ are complementary (the acute angles of a right triangle are complementary)
