An angle is one fifth of its supplement. The measure of the angle is:
- 15º
- 30º
- 75º
- 150º
The angles of a triangle are in the ratio 2 : 3 : 4. The largest angle of the triangle is:
- 120º
- 100º
- 80º
- 60º
If one angle of a triangle is equal to the sum of the other two angles, then the triangle is:
- An isosceles triangle.
- An obtuse triangle.
- An equilateral triangle.
- A right triangle.
