Let us understand
what are similar triangles,
In general, to prove that two polygons are similar, you must show that
all pairs of corresponding angles are equal and that
all ratios of pairs of corresponding sides are equal. In triangles, though, this is not necessary.
Two
angles of one triangle are equal to two angles of another
triangle, then the triangles are similar.
Example 1: Use Figure 1 to show that the triangles are similar.

AA Similarity Postulate, Δ ABC ∼ Δ DEF. Additionally, because the triangles are now similar,
Hope the above explanation helped you.
