Answer:
1. JMN is perpendicularly bisected
2.JMK and JKN are right triangles
3.∠JKM is a right angle
4. ∠1 and ∠2 are complementary
Step-by-step explanation:
1. Reasoning: Given
2. Reasoning: Definition of a perpendicularly bisected triangle.
3. Reasoning: Definition of a right triangle
4. Reasoning: Triangle Sum Theorem.
Explanation of 4: Because of the Triangle Sum Theorem, which dictates the interior angles of a triangle add up to 180, the other two angles have to add up to 90 or face violating the theorem. Angles that add up to 90 are complementary.
