One angle of a triangle is equal to the sum of the other two angles of that triangle. The two smaller angles are in the ratio 2:3. What are the angles of triangle?

By giving a counter example, show that the following statements are not true p: If all the angles of a triangle are equal, then the triangle is an obtuse angled triangle

Draw a quadrilateral and mark any two outer angles. Is thére any relation between the sum of these two and the inner angles at the other two vertices?

In a right angle triangle, the two smaller angles are in the ratio 1: 4 . Compute these angles.
