Question

∆ABC is rotated 100° counterclockwise about point P to create ∆A'B'C'. what is angle m C'A'B'?

Answer 1

The answer would be c, 70

Answer 2

Answer:

Option C.

Step-by-step explanation:

A triangle ABC is rotated counterclockwise (about a point P) by an angle = 100° to create a new triangle A'B'C'.

After rotation points A,B and C will overlap A', B' and C' respectively but angles A, B and C of triangle ABC will remain unchanged.

Therefore, ∠C'A'B' ≅ ∠CAB ≅ 70°

Option C will be the answer.
