Please help! Polygon ABCDE rotates 45° clockwise about point F to form polygon FGHIJ, shown in the figure. Find the measure of e ach angle of polygon ABCDE.
mABC=?
mBCD=?
mDEA=?
mCDE=?
All 4 questions are either 90, 117, or 127
1 answer:
Answer:
mABC = 117 degrees
mBCD = 90 degrees
mDEA = 90 degrees
mCDE = 127 degrees
Step-by-step explanation:
Since ABCDE is congruent/equal to FGHIJ, then each angle corresponds with the angle in the other shape. I.E., A = F, B = G, C = H, etc. Finding the angle for ABC is finding the angle for FGH. This works only because there was no changing the places of the points individually. :)
