Answer:
m∠A = m∠O ⇒ answer A
Step-by-step explanation:
* Lets explain how to solve the problem
- When two triangles are congruent then:
# Their corresponding sides are equal
# Their corresponding angles are equal
# Their areas are equal
- Ex: If Δ XYZ ≅ Δ LMN
∴ XY = LM , YZ = MN , XZ = LN
∴ m∠X = m∠L , m∠Y = m∠M , m∠Z = m∠N
∴ P of Δ XYZ = P of Δ LMN
∴ A of Δ XYZ = A of Δ LMN
* Lets solve the problem
∵ Δ CAT ≅ Δ DOG
∴ CA = DO , AT = OG , CT = DG
∴ m∠C = m∠D , m∠A = m∠O , m∠T = m∠G
* Look to the answer to chose the right answer
- The right answer is answer A
∴ m∠A = m∠O
