Angle Facts Angles form when two rays meet at a common endpoint. The meeting point of two rays is called the vertex.

Angles are named either by one letter assigned to the vertex (∠G) or three letters with the vertex in the center and the other two letters denoting the rays (∠RGH).

Angles are measured in units called degrees.

Angles are classified by size.

Right angles Straight angles Acute angles Obtuse angles

Page 6: Bellwork

Right Angles Angles that measure exactly 90º

Page 7: Bellwork

Straight Angle An angle that measures exactly 180º

Page 8: Bellwork

Acute Angles

Angles that measure less than 90º

Page 9: Bellwork

Obtuse Angles Angles that measure more that 90º

MEASURING ANGLES

Protractors have two sets of numbers going in opposite directions.

Be careful which one you use.

Think: Should the angle I am measuring be larger than 90 or smaller?
