This document defines and provides examples of different types of angles, including acute, right, obtuse, straight, complementary, supplementary, bisected, vertical, and linear pair angles. It explains that acute angles are less than 90 degrees, right angles are 90 degrees, and obtuse angles are greater than 90 degrees. Complementary angles add up to 90 degrees, while supplementary angles add up to 180 degrees. Bisected angles have a line dividing them evenly at the vertex. Vertical angles are the same measure and across from each other at a shared vertex. A linear pair consists of two angles next to each other that share a side and vertex.

2. Acute angle This is an acute angle because the angle it is pointing to is less then 90 degrees

3. Right Angle This is a right angle because the angle is about 90 degrees

4. Obtuse angle This angle is obtuse because it is greater then 90 degrees

5. Straight Angle This is a straight angle because it is a straight line

6. Complementary Angles These angles are complementary because together they add up to 90 degrees

7. Supplementary Angles These angles are supplementary because they add up to 180 degrees

8. A bisected angle This angle is bisected because there is a line going in the exact middle starting from the same vertex

9. Vertical Angels These angles are vertical because they are the same measure and are across from each other, sharing the same vertex.

10. Linear pair This is a linear pair because its two angles that share a side and a vertex (next to each other)
