Angles by Mind Map: Angles

1. Adjacent Angles

1.1. share same ray

1.1.1. means "next to"

2. Semicircle

2.1. 180 degrees

2.1.1. supplementary

2.1.1.1. New node

2.2. supplementary

2.2.1. sum of 2 angles equal 180 degrees

2.2.2. when adjacent to each other, they form a straight line

3. Right Angle

3.1. 2 rays are perpendicular

3.2. complementary

3.2.1. sum of 2 angles equal 90 degrees

3.3. 90 degrees

4. 2 line segments

4.1. all angles are supplementary and adjacent

4.1.1. all angles should equal 360 degrees

4.2. only 2 adjacent/ supplementary angles equal 180 degrees

4.2.1. known as Straight Angle

4.2.2. to find other angle measurements, subtract: 180-given angle

4.3. vertical angles

4.3.1. always equal

5. Measuring

5.1. one side on 0 degrees line

5.2. other line determines angle measurement

5.3. vertex is at the center of the protractor
