Introduction || Corresponding sides OF similar triangles are proportional but angle are same || Condition for two figure are similar

SAS Similarity Criterion: If in two triangle; one pair of corresponding sides are proportional and the included angles are equal then two triangles are similar.

If two corresponding sides of two similar triangles are in the ratio 9:4 , then what is the ratio of their areas?

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

If the ratio of corresponding sides of similar triangles is 3 : 4 , then the ratio of their areas is

If the ratio of corresponding sides of two similar triangles is 5 : 6, then find ratio of their areas.

If corresponding sides of two similar triangles are in the ratio 4 : 5 , then corresponding medians of the triangles are in the ratio 4 : k . Find K .

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.

Is it true to say that, if in two triangles, an angle of one triangle is equal to an angle of another triangle and two sides of one triangle are proportional to the two sides of the other triangle, then the triangles are similar? Give reason for your answer.

The corresponding sides of two similar triangles are in the ratio 3:4, then the ratios of the areas of triangles is ………….. .
