Question

Is a 90° counter clockwise rotation about the origin and then 180° rotation about the origin same as 180° rotation about the origin

Answer 1

Answer:

I wouldn't think so because in the screenshots below, the first one of a 90° clockwise rotation then of a 180° clockwise rotation, the second one of a 180° clockwise rotation, you can tell they're not in the same spots, therefore our answer would be no, a 90° then a 180° rotation is NOT the same as a 180° rotation around the origin

Answer 2

Answer:

No.

Explanation:

A 270°-clockwise rotation [90°-counterclockwise rotation] plus a 180°-rotation is the exact same as a 270°-counterclockwise rotation [90°-clockwise rotation]:

$-90° + 180° = 90°$
