Question

"Which statement is necessarily true if BD is an altitude to the hypotenuse of right ΔABC?

Answer 1

This is the TRUE statement based on the given image. A.) ΔADB≅ΔBDC 

Triangle ADB:
Angle D = 90°
Angle B = 90°/2 = 45°
Angle A = 180° - 90° - 45° = 45°

So Triangle ADB is 90-45-45 triangle. 

Triangle BDC
Angle ? = 90° This is the angle that is adjacent to Angle D. It is also supplementary to Angle D.
Angle B = 90°/2 = 45°
Angle C = 180° - 90° - 45° = 45°

So, Triangle BDC is also a 90-45-45 triangle.

Answer 2

Answer:

A

Step-by-step explanation:

This is the TRUE statement based on the given image. A.) ΔADB≅ΔBDC 

Triangle ADB:

Angle D = 90°

Angle B = 90°/2 = 45°

Angle A = 180° - 90° - 45° = 45°

So Triangle ADB is 90-45-45 triangle. 

Triangle BDC

Angle ? = 90° This is the angle that is adjacent to Angle D. It is also supplementary to Angle D.

Angle B = 90°/2 = 45°

Angle C = 180° - 90° - 45° = 45°

So, Triangle BDC is also a 90-45-45 triangle.
