Question

Which postulate or theorem can be used to prove

AABD ACBD?

F. Side-Angle-Side
G. Angle-Side-Angle
H. Side-Side-Side
J. Angle-Angle-Side
K. The triangles are not congruent.

Answer 1

F. side-angle-side

Explanation:

the answer is F because side AB is congruent to CB (side)

the angle is given that m<ABD is 90 degrees which also means m<CBD is also 90 degrees. (angle)

segment BD is a reflexive property (side)
