If triangle ABC is congruent to triangle DEF, find the angle equal to angle A.
Answer:
D
- Triangle ABC is congruent to triangle DEF.
- Remember: Two triangles are congruent if each angle of one triangle is equal to the corresponding angle of the other triangle, and each side of one triangle is equal to the corresponding side of the other.
- Triangle ABC is congruent to triangle DEF.
So, A=D,B=E, and C=F. - Thus, the side equal to A is D.
