  3. 12-18:50min

  4. This worksheet was printed for students.

  5. What is the angle relationship? How are their measures related? What equation would you use to solve for x? What is the value of x? What is the measure of each angle?

  6. What is the angle relationship? How are their measures related? What equation would you use to solve for x? What is the value of x? What is the measure of each angle? corresponding angles 15° 165° congruent angles, so equal measures 165° 15° 15° 165° 4x -13 = x + 8 15° 165° 4x -13 = x + 8 -x -x 3x -13 = 8 +13 +13 3x = 21 3 3 x = 7 x = 7 See diagram

  7. What is the angle relationship? How are their measures related? What equation would you use to solve for x? What is the value of x? What is the measure of each angle?

  8. What is the angle relationship? How are their measures related? What equation would you use to solve for x? What is the value of x? What is the measure of each angle? same-side interior angles 53° 127° supplementary angles, so measures add to 180 degrees 127° 53° 127° 53° 127° 53° x + 20 + 4x - 5 = 180 x + 20 + 4x - 5 = 180 5x + 15 = 180 -15 -15 5x = 165 5 5 x = 33 x = 33 See diagram

  9. What is the angle relationship? How are their measures related? What equation would you use to solve for x? What is the value of x? What is the measure of each angle?

  10. What is the angle relationship? How are their measures related? What equation would you use to solve for x? What is the value of x? What is the measure of each angle? alternate exterior angles 137° 43° congruent angles, so equal measures 43° 137° 43° 137° 7x -3 = 6x + 17 43° 137° 7x -3 = 6x + 17 -6x -6x x - 3 = 17 +3 +3 x = 20 x = 20 See diagram

  12. Good Morning! 01/12/22 To Do: Agenda: Outcome & HW

  13. Warm-Up Name- _________________________ and m 2. Solve for the value of w.

  14. Answers to Warm-up Warm-Up Name- _________________________ and m 2x - 16 + 5x + 28 = 180 7x + 12 = 180 -12 -12 7x = 168 7 7 x = 24 Angle A: 2x - 16 2(24) -16 48 - 16 32 The measure of angle A is 32 degrees. 2. Solve for the value of w. w +1 + 91 = 180 w +92 = 180 -92 -92 w = 88 w = 88 The two angles shown are supplementary.

  15. Angle Relationships- So True, So False! • <1 and <4 are vertical angles.

  16. Angle Relationships- So True, So False! True - they are the opposite angles on either side of the “X”. • <1 and <4 are vertical angles.

  17. Angle Relationships- So True, So False! 2. Complementary angles add up to 180 degrees.

  18. Angle Relationships- So True, So False! 2. Complementary angles add up to 180 degrees. False - Complementary angles add up to 90 degrees. It is the supplementary angles that add up to 180 degrees.

  19. Angle Relationships- So True, So False! 3. Angles over 90 degrees are acute.

  20. Angle Relationships- So True, So False! 3. Angles over 90 degrees are acute. False - Angles over 90 degrees are obtuse. Acute angles are angles that are less than 90 degrees.

  21. Angle Relationships- So True, So False! 4. <1 and <8 are alternate interior angles.

  22. Angle Relationships- So True, So False! False - they are alternate EXTERIOR angles because they are outside of the parallel lines. 4. <1 and <8 are alternate interior angles.

  23. Angle Relationships- So True, So False! 5. <3 and <7 are corresponding angles.

  24. Angle Relationships- So True, So False! True - Corresponding angles are in the same position with one on each of the parallel lines. 5. <3 and <7 are corresponding angles.

  25. Angle Relationships- So True, So False! 6. If the measure of <8 is 105 degrees then the measure of <2 is 75 degrees.

  26. Angle Relationships- So True, So False! True - If we use the 105 degrees to fill in the diagram, then the measure of angle 2 is 75 degrees. 105 75 75 105 105 75 75 105 6. If the measure of <8 is 105 degrees then the measure of <2 is 75 degrees.

  27. Angle Relationships- So True, So False! 7. <1 and <2 are congruent to each other.

  28. Angle Relationships- So True, So False! False - angles 1 and 2 are not the same size. Together they form a straight line, so they add to 180 degrees. Angle 1 is obtuse and angle 2 is acute. 7. <1 and <2 are congruent to each other.

  29. Angle Relationships- So True, So False! 8. < 4 and <5 are alternate interior angles.

  30. Angle Relationships- So True, So False! True - They are both inside the parallel lines and they are on alternate sides of the transversal. They are congruent. 8. < 4 and <5 are alternate interior angles.

  31. Angle Relationships- So True, So False! 9. Lines B and C are perpendicular.

  32. Angle Relationships- So True, So False! False - Lines B and C are parallel because they will never intersect. Perpendicular lines form right angles. 9. Lines B and C are perpendicular.

  33. Angle Relationships- So True, So False! 10. <2 and <6 are congruent to each other.

  34. Angle Relationships- So True, So False! True - They are corresponding angles which makes them congruent when lines are parallel. 10. <2 and <6 are congruent to each other.
