  1. Lesson 4: Angle Measure Chapter 1: Tools of Geometry

  2. Degree- the unit of measurement for an angle • Ray- a part of a line which has one endpoint and one end that extends infinitely (name with the endpoint first and then any other point on the ray) • Opposite rays- two rays that share an endpoint and extend in opposite directions (together they make a line) • Angle- formed by two non-collinear rays that have a common endpoint • Sides of an angle- rays • Vertex- the common endpoint of the rays of an angle • Angle Bisector- a ray or line that divides an angle into two congruent angles Definitions

  3. Naming and Classifying Angles A Angle: -B is the vertex -ray BA and ray BC are the sides( BA and BC ) -Angle names: ABC, CBA B, 4 -Angle bisector : makes 2 congruent angles 4 B C

  4. C. A. Name all angles that have B as a vertex. B.Name the sides of5. Examples

  5. A. Measure TYV and classify it as right, acute, or obtuse. B.Ray YT bisects angle SYU. Angle TYS = 2x-24, angle UYT = x+16. Find x and the measure of angle SYU. Examples
