5. 1.4 Angle Measure Thursday, October 6

6. Objective, Homework • SWBAT • Measure, classify, and identify acute, right, obtuse, and congruent angles • Apply knowledge of solving expressions to measuring angles • Homework • Section 1.4 pgs 34, 36 (13-27 odd, 35-39 odd, 63) • 12 problems

7. Definitions • TAKE NOTES!!!!!

8. Ray • A ray is a part of a line • It has one endpoint and extends indefinitely in one direction • Named using the endpoint and any other point on the ray with a  over the two points → → GH AB

9. Quick Understanding Check • A ray can be named with • 1 point • 2 points • 3 points • 4 points • A ray must have ___ over the point(s) • Nothing • –– • ↔ • →

10. Quick Understanding Check • A ray can be named with • 1 point • 2 points • 3 points • 4 points • A ray must have ___ over the point(s) • Nothing • –– • ↔ • →

11. Naming is Important

12. Opposite Rays • If you choose a point on a line, that point determines two rays called opposite rays • Opposite rays form a line • Point T determines to rays, what are they?

13. Angle • An angle is formed by two noncollinear rays that have a common endpoint • The sides of an angle are rays • The common endpoint is called the vertex • Named using ∠ + the vertex point or ∠ + (Point on 1 side)(Vertex point)(Point on other side) These angles could be named: ∠1 or ∠x or ∠BAC or ∠CAB

14. Protractor and Degrees • Protractor is used to measure angles • Place center point on vertex • Align the straight line with one side • Degrees are the unit of measure for angles • 1° = 1/360 of a circle • The measure of an angle is written m ∠4 = ___° m ∠ABC = ___°

15. Types of Angles • Right angle is an angle that measures exactly 90 degrees • m ∠XYZ = 90° • Acute angle is an angle that measures less than 90 degrees • m ∠PQR < 90° • Obtuse angle is an angle that measures more than 90 degrees and less than 180 degrees • 180 ° > m ∠CAB > 90°

16. Practice • Refer to the figure • Name the vertex of ∠4 • Name the sides of ∠BDC • Write another name ∠DBC • Classify each angle in the figure as right, acute, or obtuse • ∠MPR • ∠RPN • ∠NPS

17. Congruent Angles • Angles that have the same measure are congruent angles • Arcs on the figure also indicate which angles are congruent • ∠A ∠B • All right angles are congruent

18. Angle Bisectors • A ray that divides the angle into two congruent angles is called an angle bisector

19. Practice: Read and understand the problem

20. Exit Slip • Directions use the bottom of your Bell Ringer • What did we learn in this lesson? • What do I want to understand better?

21. Homework • Section 1.4 pgs 34, 36 (13-27 odd, 35-39 odd, 63)
