One angle of a triangle is equal to one angle of another triangle and the bisectors of these two equal angles divide the opposite sides in the same ratio, prove that the 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.

If one angle of a triangle is equal to the sum of the other two angles, then the triangle is

If one of the angles of a triangle is 130^(@) , then the angle between the bisectors of the other two angles can be

Theorem 6.5 : If one angle of a triangle is equal to one angle of the other triangle and the sides including these angles are proportional, then the two triangles are similar.

If the bisector of an angle of a triangle bisects the opposite side, prove that the triangle is isosceles.

The external angle bisector of an angle of a triangle divides the opposite side externally in the ratio of the sides containing the angle.

The three angles of a triangle are equal to one another. What is the measure of each of the angles?

One of the angles of a triangle has measure 80^0 and the other two angles are equal. Find these two angles.

One of the angles of a triangle has measure 80^0 and the other two angles are equal. Find these two angles.

If one angle of a triangle is equal to the sum of the other two, show that the triangle is a right triangle.
