Question
In each of the given pairs of triangles, find which pair of triangles are similar. State the similarity criterion and write the similarity relation in symbolic form:
Solution
In Δ ABC
∠A + ∠šµ+ ∠š¶=1800 (Angle Sum Property)
ā¹80°+ ∠šµ+700=180°
ā¹ ∠šµ=30°
∠š“= ∠š ššš ∠šµ= ∠š
Therefore, by AA similarity , Δ ABC - Δ MNR
