Question

Hey so me and my friends answered this together but our teacher said it was wrong and i wanted to see how others answered instead

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.

please actually answer.

Answer 1

1. REFLECTION 2. ROTATION 3. B' and B''? bc they are the same? (didnt really get the question) 4. 26.3

Step-by-step explanation: meh

Answer 2

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, because if you flipped ABCD over the y axis, you would get 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 because if you rotate A'B'C'D 90 degrees clockwise, you get A"B"C"D".

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

All <B's and <C's would be congruent. From just looking at them, they look congruent.

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

The perimeter is 26.3.

If you add up the lengths of the sides, 6 + 6 + 8 + 6.3 = 26.3

I hope this helps!
