Answer the questions to describe the transformations of figure ABCD 1. Is A’B’C’D’ a translation, rotation, or reflection of ABCD? Explain how you can tell.

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

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

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

1. Reflection

2. rotation and reflection

3. b', b''

4. 26.3

Step-by-step explanation:

1. It is like looking in a mirror. Its is being reflected across the y axis

2. It is rotated 90 degrees to the right. Then reflected over the x axis.

3. they are the same

4. It is the same as A" B" C" D" so the lengths are the same and you just add them.

HOPE THIS HELPS!!!

btw,im not 100% sure on them all :)

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

i think the answer is d im not sure
