Question

For the diagram below, if the two triangles are congruent and side BC = 12, then what is the length of side EF?

Answer 1

b. 12

Step-by-step explanation:

We are told that the two triangles are congruent. This means that they are exact copies of each other.

Now for triangle ABC, the side BC is the same as the side EF in the triangle DEF. This means BC = EF.

Since BC measures 12 units, then the length of EF is also 12 12 units.

Therefore, choice b is the correct answer.
