Angles & Polygons

To have an angle, you need...

• two rays

• two rays and a vertex

• two rays that join at a point called vertex

• two rays that join at a point called vertex and a protractor

How are single angles classified?

• By their position in a polygon

• By their measure in degrees

• By their sum in a triangle

• By their connection with parallel lines

Explain the concept of vertical angles.

• Vertical angles are adjacent angles formed by the intersection of two lines.

• Vertical angles are complementary angles formed by the intersection of two lines.

• Vertical angles are supplementary angles formed by the intersection of two lines.

• Vertical angles are opposite angles formed by the intersection of two lines. They measure the same.
