Are the two triangles similar?
Tpy6a [65]

Answer:

Option B Yes by AAA

Step-by-step explanation:

we know that

If the two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent

so

\frac{HM}{MK}=\frac{GM}{MJ}

substitute the values and verify

\frac{8}{12}=\frac{6}{9}

simplify

\frac{2}{3}=\frac{2}{3} -------> is true

therefore

The triangles are similar by AAA------> the three angles are congruent
