Question

Sam rotated parallelogram ABCD 270 counter clockwise around the origin if angle a is 120 and angle B 60 what is the degree measurement of angle B

Answer 1

Given that ABCD is a parallelogram.

where angle B is 60 degree.

Notice that only parallelogram is rotated. Rotation doesn't changes the name of angles. So angle B will remain at it's position.

Hence value of angle B will also not change.

So final answer for the value of angle B is 60 degree.
