Question

Point B has 3 lines extending from it. One line extends to point A, another to C, and another to D. Angle A B D is a right angle.
Which information do you know is true from the diagram? Check all that apply.

∠ABD is a right angle.
Ray B C bisects angle ∠ABD.
m∠ABC = 45°
m∠CBD = 45°
m∠ABD = 90°

Answer 1

Select only:
- ∠ABD is a right angle. (True — given.)
- m∠ABD = 90°. (True — same statement in degree form.)

Not enough information to conclude Ray BC bisects ∠ABD or that m∠ABC = 45° or m∠CBD = 45° — those would require BC to be stated as the angle bisector, which is not given.
