Question

Polygon ABCDE rotates 45° clockwise about point F to produce polygon FGHIJ as shown. What is mBCD?

45°
117°
127°
172°

Answer 1

m∠ABC = 117°

m∠BCD = 127°

m∠DEA = 90°

m∠CDE = 127°

Answer 2

From my point of view diagram , the image attached is the image of the given figure. As the figure is only rotated, the measure of the angles of the shape does not change. So comparing similar angles, mBCD should be equal to mGHI which is 127 degrees.
