Question

An angle of size 124° has been rotated d degrees around a center O. What is the size of the rotated angle? How do

you know?
A) 124°, Corresponding angles are equal.
B) 124°, Vertical angles are equal.
C) 180° - d, Exterior angles are supplementary.
D) d, Interior angles are complementary.

Answer 1

The size of a rotated angle remains the same as the original angle, so the answer is A) 124°, because corresponding angles are equal.

Step-by-step explanation:

The student is asking about the size of an angle after it has been rotated around a center point, which is a concept in geometry. When an angle is rotated, the size of that angle remains the same. This is because the measure of an angle is determined by the amount of rotation from the initial side to the terminal side, which does not change during a rotation about the center. Therefore, the correct answer to the question is A) 124°, because corresponding angles are equal. The other options B) through D) are not applicable to this situation.
