Question

1. The sum of all angles formed on the second side of a line at a point on the line is.................


2. The sum of all angles about a point is.................

3. Two obtuse angles cannot form a ............... of angle.


4. The complement of 2/3 of a right angle is.................


5. If the sum of two adjacent angle is 180o, then the non-common arm of the angle form a............
​

Answer 1

• The sum of all the angles formed on the same side of a line AB at a point O on it is 180°.
• The sum of all angles about a point is 360°
• No, two obtuse angles cannot form a supplementary angle. By the definition of obtuse angles, the angles that measure greater than 90° are obtuse. If you add two obtuse angles, the sum will be greater than 180°
• The complement of 2/3 of a right angle is..30
• ...... If the sum of two adjacent angle is 180o, then the non-common arm of the angle form a...line...

Answer 2

1 - 180

2 - 360

3 - Supplementary

4 - 30

5 - line
