Question

Quadrilateral H’ is the image of quadrilateral H after a sequence of transformations. If quadrilateral H’ is congruent to quadrilateral H, which transformations could have been used ?

A dilation by a scale factor of 2 followed by a reflection
A rotation followed by a dilation by a scale factor of 1/2
A reflection,a translation of 1 unit left, and then a dilation by a scale factor of 3
A translation of 6 units down a rotation and then a reflection

Answer 1

the last one is correct



A translation of 6 units down a rotation and then a reflection






good luck

Answer 2

Answer: A translation of 6 units down a rotation and then a reflection

Explanation:

• The rigid transformations preserves the side length and angle measure of a figure such that figure doesn't shrink or get enlarger. It creates congruent figures.

• There are four rigid transformations such as :

a) reflections, b) rotations, c) translations and d) glide reflection.

• A dilation changes the size of the image when the scale factor is not equal to 1. It does not creates congruent images.

Hence, if quadrilateral H’ is congruent to quadrilateral H, then the transformation must be :

A translation of 6 units down a rotation and then a reflection.
