Question

Triangles ABC and GHJ are congruent. mA = 150º. mB = 15º. What are the measurements of GHJ?
A.mG = 150º
mH = 15º
mJ = 15º

B.mG = 15º
mH = 115º
mJ = 15º

C.mG = 45º
mH = 125º
mJ = 10º

D.mG = 15º
mH = 125º
mJ = 15º
ALSO, what does this "M" Stand for?

Answer 1

m usually stands for "The measurement of ..." a given angle. :)

Answer 2

well, that slves HALF of ther problem, now..what abuot the other half?
