Question

1. which of the following statements is true about the congruent triangles below?

∠a = ∠d
∠c = ∠e
bc ≅ ed
ac ≅ ef

Explanation:

Step1: Identify congruent - part markings

In congruent triangles, same - number of tick marks on sides mean they are congruent and same - number of arcs on angles mean they are congruent.

Step2: Analyze side congruence

By observing the tick - marks on the sides of the triangles $\triangle ABC$ and $\triangle FDE$, we can see that $\overline{AC}$ and $\overline{EF}$ have the same number of tick - marks.

Answer:

$\overline{AC}\cong\overline{EF}$
