The measures of two adjacent angles of a parallelogram are in the ratio 3:2 . Find the measure of each of the angles of the parallelogram.

The angles of a triangle are in A.P. and the ratio of number of degree in the least angle to the number of radian in the greatest angle is 60 :pi . Find the angles in degree.

Corresponding sides of two similar triangles are in the ratio 2:3 . If the area of the similar triangle is 48 cm^2 , find the area of the larger triangle.

If the altitude of two similar triangle are in the ratio 2:3 what is the ratio of their areas?

The measures of the angles of a triangle are in A.P. If the greatest angle is double the least angle, express the angles of the triangle in degree and radian.

The sides of a triangle are 7,4 sqrt3 and sqrt13 cms . Find the smallest angle

Prove that the areas of two similar triangles are in the ratio of the squares of their corresponding angle bisector.

The sides of a right angled triangle are in G.P.Find the common ratio.

If A(5,-1),B(-1,7) and C(1,2) are the verticles of a triangle find the equation of the internal bisector of angleA

If one angle of a triangle is equal to one angle of another triangle and the bisectors of these equal angles divide the opposite side in the same ratio then show that the triangle are similar.
