  2. 1-4 Measuring Angles Objective: To find and compare the measures of angles

  3. Warm up: True/False? The angle on the right is larger than the angle on the left?

  4. Formed by two rays w/ the same endpoint • Name it: • By the vertex (only when there is only 1 angle drawn. • symbol and 3 letters with the vertex in the middle. • symbol and a number (if provided) Angles

  5. Problem 1 (a) (b) (c)

  6. Problem 1-Got it? (a) What are two other names for 1? What are two other names for KML? Would it be correct to name any of the angles m? Explain.

  7. Types of Angles

  8. Protractor Postulate Consider OB and a point A on one side of OB. Every ray of the form OA can be paired one to one with a real number from 0 to 180.

  9. How do you suppose you find the measure of COD?

  10. Problem 2 What are the measures of <LKN, <JKL, and <JKN? Classify each angle as acute, right, obtuse, or straight.

  11. <LKN = __________________________ and is ____________. <JKL = __________________________ and is ____________. <JKN = __________________________ and is ____________.

  12. Problem 2- Got it ? What are the measures of <LKH, <HKN, and <MKH? Classify each angle as acute, right, obtuse, or straight.

  13. <LKH = __________________________ and is ____________. <HKN = __________________________ and is ____________. <MKH = __________________________ and is ____________.

  15. Solutions

  16. 1-4 Measuring Angles Continued Objective: To find and compare the measures of angles

  17. Warm up:

  18. Congruent Angles • Angles with the same measure If B If the measures of the angles are the same, then the angles are congruent.

  19. Note: The arcs indicates if angles are equal. It does not matter how big the arcs are.

  20. Synchronized swimmers form angles with their bodies, as shown in the photo. If mGHJ = 90, what is mKLM? Problem 3

  21. What do you think you can conclude from this diagram?

  22. Angle Addition Postulate If point B is in the interior of ∠AOC, then mAOB + mBOC = m AOC.

  23. If mRQT = 155, what are mRQS and mTQS? Problem 4

  24. Problem 4- Got it ? DEF is a straight angle. What are mDEC and mCEF?
