Question

PLEASE HELP Is A'B'C'D' a translation, rotation, or reflection of ABCD? Explain how you can tell.

Answer 1

A’B’C’D’ is a reflection.

It is a reflection because it’s mirrored across the y-axis, like looking at the side of your face in the mirror. A translation is the same thing and moving it from one set of coords to another, without turning it. A rotation would be turning it, which A’B’C’D’ is neither of.

Answer 2

Answer:

1. Is A'B'C'D' a translation, rotation, or reflection of ABCD? Explain how you can tell.

A'B'C'D' is a reflection over the y-axis. By flipping ABCD over the y-axis, the result will be A'B'C'D'

2. Is A"B"C"D" a translation, rotation, or reflection of A'B'C'D'? Explain.

A"B"C"D" is a rotation of A'B'C'D'. This is proven by the fact that if A'B'C'D' is rotated 90 degrees, the result will be A"B"C"D".

3. Suppose the measure of ∠B is 89°. Which other angles must measure 89°? How do you know?

If ∠B measures 89 degrees, then all other B angles must also measure 89 degrees because the angle is not changed by any of the transformations performed.

4. What is the perimeter of A"B"C"D"? Explain how you found the perimeter.

Because the size and shape are not any different from the original figure, the perimeter is 26.3 units.

6+6+6.3+8=26.3
