Question

from unit 2, lesson 3. triangle abc is congruent to triangle edf. so mei knows that there is a sequence of rigid motions that takes abc to edf. select all statements that are true after the transformations. a angle a coincides with angle e. b angle b coincides with angle f. c segment ab coincides with segment ef. d segment bc coincides with segment df. e segment ac coincides with segment ed.

Explanation:

Step1: Recall congruent - triangle property

When $\triangle ABC\cong\triangle EDF$, corresponding angles and sides are equal. That is, $\angle A$ corresponds to $\angle E$, $\angle B$ corresponds to $\angle D$, $\angle C$ corresponds to $\angle F$, $AB$ corresponds to $ED$, $BC$ corresponds to $DF$, and $AC$ corresponds to $EF$.

Answer:

A. Angle A coincides with angle E.
D. Segment BC coincides with segment DF.
