1.4 Measure and Classify Angles

Definitions

Angle – consists of two different rays with the same endpoint.

vertex

The rays are the sides of the angle.The endpoint is the vertex of the angle.

sides

This angle can be named BAC or CAB or A.

Classifying Angles

Acute Angle: less than 90º

Right Angle: equals 90º

Obtuse Angle: more than 90º

Straight Angle: equals 180º

Page 4: 1.4 Measure and Classify Angles. Definitions Angle – consists of two different rays with the same endpoint. B C vertex The rays are the sides of the angle

Angle Addition Postulate

If P is in the interior of RST, then

m RST = m RSP + m PST

Page 5: 1.4 Measure and Classify Angles. Definitions Angle – consists of two different rays with the same endpoint. B C vertex The rays are the sides of the angle

Congruent Angles

Two angles are congruent if they have the same measure.

A B

24º 24º

so A = B~m A = m B
