Answer:
see explanation
Step-by-step explanation:
If the ratios of the 3 pairs of corresponding sides of the 2 triangles are equal then the triangles are similar
[tex]\frac{15}{5} [/tex] = [tex]\frac{12}{4} [/tex] = [tex]\frac{9}{3} [/tex] = 3
Then the triangles are similar by the SSS postulate

If 2 angles of 1 triangle are congruent to 2 angles of another triangle then the triangles are similar
∠ A = ∠ p = 27°
∠ B = ∠ Q = 45°
Then Δ ABC and Δ PQR are similar by the AA postulate
