Measure and classify angles. Use angle bisectors to calculate angle measures.
Angle: Two rays joined at a common endpoint.
Vertex: Point at which the two rays meet.
Acute Angle: Angle that measures less than 90º.
Obtuse Angle: Angle that measures great than 90º but less than 180º.
Right Angle: Angle that measures 90º exactly.
Straight Angle: Angle that measures 180º exactly, a straight line.
Angle Bisector: A ray that divides the angle exactly in half.
∠ = symbol for angle
≅ = symbol for congruent
m∠A = the measure of angle A, a numerical value in degrees, such as 60°
