How would I solve this problem?
The triangles are similar by SSS similarity criterion:Let, the first triangle = Δ ABCSecond triangle = Δ PQRthen, Δ ABC = 3 × Δ PQRTheir sides are proportional to each other, and gives three when dividing smaller triangle side with corresponding side of larger triangleHope this helps!
The criterion is that:The ratio of corresponding sides of both triangles are the same. 8/24 = 1/34/12 = 1/312/36 = 1/3So both triangles are similar, because ratio of corresponding sides are the same.
