  2. Section 1-4: Angle Measure

  3. Ray E F G Has one endpoint and extends forever in the other direction Opposite rays Q P R Share an endpoint and continue in opposite directions. Opposite rays are collinear.

  4. Angles Are created by 2 non-collinear rays that have a common endpoint. Are made up of sides and a vertex. side AB B 4 vertex A A C side AC

  5. Angles CONT'D Angle Bisector – a ray that divides an angle into 2 congruent angles. Congruent angles – have the same measurement.

  6. Example 1 Example 2 S R T E 3 1 D 2 P Q A B C • Name all angles that have R as a vertex. • b. Name the sides of 1 • Classify each angle as right, acute or obtuse. • ABD • DBC • EBC

  7. Refer to the figure • Name the vertex of 4. • Name the sides of BDC. • Write another name for DBC. B A 4 3 1 2 C D • Classify each angle as right, acute or obtuse. • MPR • RPN • NPS N M S P R

  8. QS bisects PQT, and QP and QR are opposite rays. • If m PQT = 60 and m PQS = 4x + 14, find the value of x. • If m PQS = 3x + 13 and m SQT = 6x – 2, find m PQT T S` Q P R

  9. BA and BC are opposite rays, BF bisects CBE, and BD bisects ABE. • If m EBF = 6x + 4 and m CBF = 7x – 2, find m EBC • If m 1 = 4x + 10 and m 2 = 5x, find m 2. • If m 2 = 6y + 2 and m 1 = 8y – 14, find m ABE. • Is DBF a right angle? Explain. E D F 2 3 1 4 B A C
