**Proportional Segments**Unit 6**Corresponding Angles**Alternate Interior Angles**Let’s go over your HW.**• What is the number of the vertical angle of 3? • 2 • What is the number of the corresponding angle of 3? • 7 • What is the number of the alternate interior angle of 3? • 6 • What is the number of the same side interior angle of 3? • 5 • The number of the supplementary angle of 3? • 1 and 4 • If m 3 were 80, what would be the m 1? • 100**Open Note Quiz**• Get out the notes that you took yesterday.**Copy the picture above.**• What are the measurements of 1 and 2? • What are the measurements that we know? • Does z have an angle relationship with 1 or 2? • Does 110 have an angle relationship with 1 or 2? • What does z equal? (Hint: z + 110 = 180) • What are the measurements of 1 and 2? z 110**Copy the picture above.**• What are the measurements of 1 and 2? • What are the measurements that we know? • Does x have an angle relationship with 1 or 2? • Does 2x have an angle relationship with 1 or 2? • What does x equal? (Hint: x + 2x = 180) • What are the measurements of 1 and 2? 7 x 2x**Write these equations.**left top = right top left total right total left top__ = right top left bottom right bottom left top__ = left total__ middle line bottom line**HW**• Algebra Applications with Angles WS • Practice with Similar Figures WS
