if cb bisects ∠acd, what additional information could be used to prove δabc ≅ δdbc using sas? check all that apply.

a) m∠abc = 125° and ab ≅ db
b) δacd is isosceles with base ad
c) δabd is isosceles with base ad
d) cd = 52 cm
e0 ab = 29 cm

The correct answers are:

A) m∠ABC = 125° and AB ≅ DB ; B) ΔACD is isosceles with base AD ; D) CD = 52 cm.

Explanation:

If we knew the measure of ∠ABC and knew that AB ≅ DB, we would have either ASA (angle-side-angle) or SAS (side-angle-side). This is because we know since CB bisects ∠ACD, ∠ACB is congruent to ∠DCB. Thus we have two angles with a side between them (CB is congruent to itself) or two sides with an angle between them.

If we know that ΔACD is isosceles with base AD, this means that AC is congruent to DC. This means that we have two sides with an angle between the, or SAS.

If we know that CD = 52 cm, this means that AC and CD are congruent. This gives us two sides with an included angle, or SAS.
