" If the corresponding angles of two quadrilaterals are equal,then they are similar."

If the correspondig angles of two quadrillaterals are equal, then they are similar.

SSS Similarity Criterion : If the corresponding sides of two triangles are proportional;then they are similar

Corresponding angles are always equal

If corresponding angles of two triangles are equal, then two triangles are called   .............

The corresponding angles of any two polygonal figures are equal.

If In two triangles, the sides of one triangle are proportional to the corresponding sides of the other triangle, then their corresponding angles are equal and hence the traingles are similar.

Prove that for a given correspondence, if three angles of one triangles are congruent to the corresponding three angles of the other triangle, then the two triangles are similar.

Prove that for a given correspondence, if three angles of one triangles are congruent to the corresponding three angles of the other triangle, then the two triangles are similar.

Theorem 6.3 : If in two triangles, corresponding angles are equal, then their corresponding sides are in the same ratio (or proportion) and hence the two triangles are similar.
