Q31 of 168 Page 4

If in two triangles ABC and DEF, , then

Given that ΔABC and ΔDEF are two triangles such that



We know that AAA similarity criterion states that in two triangles, if corresponding angles are equal, then their corresponding sides are in the same ratio and hence the two triangles are similar.


⇒ ∠A = ∠D, ∠B = ∠E, ∠C = ∠F


∴ ΔCAB ~ ΔFDE


Hence proved.
