The sides of a triangle are a, b, `sqrt(a^2+b^2+ab).`Find the greatest angle.

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

The length of the sides of a triangle are a+b , ab-1 and sqrt((a^2+1)(b^2+1)) . Show that it is a right angled triangle.

Sides of a triangle are 4, 5, 6 cms. Show that the greatest angle is twice the smallest angle.

The length of the sides of a triangle are ax-by , ay+bx and sqrt((a^2+b^2)(x^2+y^2)) . Show that it is a right angled triangle.

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 right angled triangle are in G.P.Find the common ratio.

In a right angle triangle the length of the sides adjacent to the right angle and sqrta and sqrt(1-a) . Find the length of the hypotenuse.

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.

The length of the hypotenuse of an isosceles right angled triangle is 8sqrt2 cm . Find the length of the other two sides.

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.
