Question

Triangle ABC undergoes a series of transformations to result in triangle DEF .

Is triangle DEF congruent to triangle ABC ?

Select Congruent or Not congruent for each description.

Answer 1

question 1 is congruent. 2 is not congruent and 3 is congruent

Answer 2

Answer: 1) Congruent

2) Not congruent

3) Congruent

Explanation:

We know that a rigid transformations preserves side-lengths and angle measures of a figure in such a way that the figure doesn't shrink or get enlarger. It creates congruent figures.

• The three main rigid transformations are:

a) reflections, b) rotations, c) translations

On the other hand a dilation changes the size of the image when the scale factor is not equal to 1. It does not produces congruent images.
