Question

Are the two triangles similar? How do you know?

Answer 1

Answer. C (yes; by SAS)

We know that opposite angles formed by the intersection of two lines are congruent:
Therefore, Angle HMG ≅ Angle JMK

Line HM : Line MK
= 8:12
= 2:3

Line GM : Line MJ
= 6:9
= 2:3

Therefore,
HM ≅ MK
GM ≅ MJ

Therefore, we have one pair of congruent angles, and a pair of congruent sides. 
⇒ The two triangles are congruent by SAS theorem.
