Answer:
1. obtuse angle
2. Right angle
3. Adjacent angle
4. Supplementary angle
5. Acute angle
6. Straight line
7. Complementary angle
8. Vertical Angle
9. linear
10. Vertex
Explanation:
1. Obtuse angle are angle that measures greater than 90 degree but less and 180 degree
2. Right angle are angle that measures exactly 90 degree
3. Adjacent angle are angles that has a common vertex and share a common side
4. Straight angle is a pair of angle whose sum is 180 degree.
5. Acute angle is an angle greater than 0 degree but less than 90 degree
6. straight line measure exactly 180 degree
7. Complementary angle is a pair of angle whose sum is 90 degree.
8. Vertical Angle is a pair of angle made by intercepting lines with congruent opposite side
9. Linear is a pair of adjacent, supplementary angles.
10. Vertex is an common end point that two rays meet to form an angle.
