Two polygons are similar if their corresponding angles are equal.

Find counter examples to disprove the following statements: Two triangles are congruent if all their corresponding angles are equal.

Two polygons with same number of sides are ........................ if their corresponding angles are equal and corresponding sides are equal.

Two quadrilaterals will be similar if their similar angles are square (equal/proportional) and similar sides are squares (unequal/porportional)

If a transversal intersects two lines such that the bisectors of a pair of corresponding angles are parallel, then prove that the two lines are parallel.

If two or more than two triangles be equiangular and the ratios of their corresponding sides be equal, then the triangles are called ________ triangles.

The interior angles of a polygon are in arithmetic progression. The smallest angle is 120^@ and the common difference is 5^@ . Find the number of sides of the polygon.

The areas of two similar triangles are 9 cm^2 and 16 cm^2 respectively. The ratio of their corresponding sides is

Answer any One queation : Prove that, if a perpendicular is draw on the hypotenuse from the right angled triangle, two triangles so formed on the two sides of the perpendicular are each similar to the original triangle and also similar to each other.

The corresponding angles of any two polygonal figures are equal.
