Question

Use ΔABC shown below to answer the question that follows:
What statement is needed to prove that ΔABC is similar to ΔDBA?

Segment AD is an altitude of ΔABC.

Segment CB is a hypotenuse.

Segment CA is shorter than segment BA.

Angle C is congruent to itself.

Answer 1

I think it's A

Answer 2

Ok do u know why cuz I can't figure it out

Answer 3

A is correct. If segment AD is an altitude of ABC, then angle ADB is a right angle. Since right angles are congruent and angle DBA is the included in both triangles, then from Angle-Angle similarity the two triangles are similar.

Answer 4

ok thank you
