Question

What other information is needed to prove that the two triangles congruent by SAS?

Answer 1

If we have two triangles:
Triangle GLT and Triangle NMQ and we are given that LT = MQ and  L = M, then the remaining condition to prove that the two triangles are similar by SAS, is
D. LG = MN
since LG and LT make up angle L and MQ and MN make up angle M

If we have two triangles,
triangle RST and UVW, then to prove that they are similar by SAS, these conditions must be met:
ST = UV
A. S = V
E. RS = WU
