Question

Which of these statements are correct about an angle measuring 78° in a coordinate plane? Select all that apply.

А. If it is reflected across the x-axis, it will still measure 78°.
B. If it is rotated 180° about the origin, it will no longer measure 78°
C. If it is translated 26 units to the left, it will still measure 78°
D. If it is translated 22 units down, it will no longer measure 78°
E. If it is reflected across the y-axis, it will no longer measure 78°.
F. If it is rotated 90° about the origin, it will still measure 78°

Answer 1

An angle measuring 78° in a coordinate plane has various properties when reflected, rotated, or translated.

Step-by-step explanation:

An angle measuring 78° in a coordinate plane has the following properties:

1. If it is reflected across the x-axis, it will still measure 78°.
2. If it is rotated 180° about the origin, it will no longer measure 78°.
3. If it is translated 26 units to the left, it will still measure 78°.
4. If it is translated 22 units down, it will no longer measure 78°.
5. If it is reflected across the y-axis, it will no longer measure 78°.
6. If it is rotated 90° about the origin, it will still measure 78°.
