**Warm Up**x = 14 Solve. x = 9 x = 2**Name this angle 4 different ways.** C A 2 T **Name the ways can you name 3?**Name the ways can you name 4? Name the ways can you name MHT? M A 3 4 T H**How do you name each red side?**M A E U M T H Y F L I N**Angle Addition Postulate**Why can’t you name any of the angles S? T R S P**Example 1**R T 1 P S**Adjacent Angles**Two angles are adjacent if they share a common vertex and side, but have no common interior points. SIDE BY SIDE…shoulder to shoulder. NO YES**Linear Pair**Solve for x. x 62 Equation: ____ + ____ = 180 Two angles that are side-by-side and create a straight line (add up to 180). 118**Vertical Angles**Solve for x. x 76 Equation: ______ = ______ 76 Their sides form two pairs of opposite rays (and the angles are equal to each other).**Solve for x.**50 Vertical Angles: Their sides form two pairs of opposite rays (and the angles are equal to each other).**Solve for x.**32° 1 _ x 3 96 Vertical Angles: Their sides form two pairs of opposite rays (and the angles are equal to each other).**Solve for x.**40° 100 Vertical Angles: Their sides form two pairs of opposite rays (and the angles are equal to each other).**Solve for x.**(3x + 23)° (4x + 18)° 5 Vertical Angles: Their sides form two pairs of opposite rays (and the angles are equal to each other).**Supplementary Angles**Solve for x if the following 2 angles are supplementary. x 82 Equation: ____ + ____ = 180 98 Two angles add up to 180.**Solve for x.**23 Supplementary Angles: Two angles add up to 180.**13 and 14 are supplementary angles**m13 = 47. Find m14. 133 Supplementary Angles: Two angles add up to 180.**Complementary Angles**Solve for x if the following 2 angles are complementary. x 76 Equation: ____ + ____ = 90 14 Two angles add up to 90.**Solve for x.**2x + 23 x + 13 18 Complementary Angles: Two angles add up to 90.**Review**1 5 2 4 3 no Are angles 4 and 5 supplementary angles? no Are angles 2 and 3 complementary angles? Are angles 4 and 3 supplementary angles? yes Are angles 2 and 1 complementary angles? yes
