Answer 5

Yes, Angle-Side-Angle, and Side-Angle-Side. I think it's D... but I'm unsure that's it. I can see the 90 degree angles made by "M" and "D", and the two outer sides are the same... Hmm..

Answer 6

hmm. the third parts that are identical are the parts common to the triangles. know that parts?

Answer 7

option c SAS

Answer 8

because AM=ZD(GIVEN)
angleM=angleD(GIVEN)
MD=MD(COMMON)

Answer 9

ok @Wimsicle
