Answer:
AA similarity
Explanation:
Similar triangles:
Similar triangles are the triangles that have corresponding sides in proportion to each other and corresponding angles are equal.
Similar triangles can be proved by any one of the rules, given below.
1) AA similarity
2) SAS similarity
3) SSS similarity
A represent angle and S denotes side.
In ΔABC & ΔPQR,
∠A = ∠P {Both the angles are marked by double curves}
∠B = ∠Q {Both the angles are marked by single curve}
ΔABC ~ ΔPQR by AA similarity
