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

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

  3. 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.

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

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

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

  7. 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.

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

  9. 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.

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

  11. 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.

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

  13. 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.

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

  15. 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.

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

  17. 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.

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

  19. 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.

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

  21. 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.

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

  23. 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.
