1.6+Angle+Pair+Relationships

This section will teach you the difference between vertical angles and linear pairs. It will also teach you what complementary angles and supplementary angles are. You can use this in life to figure out the measures of angles. Like the angles of cables on a bridge.

Vocab: (http://www.onlinemathlearning.com/pairs-of-angles.html)
 * Complementary Angles**:sum of angles measures 90
 * Supplementary Angles**: sum of angles measures 180

(http://www.mathreference.com/geo,vert.html)
 * Vertical Angles**: sides form two pairs of opposite rays

(http://www.icoachmath.com/sitemap/linearpair.html)
 * Linear Pair**: non-common sides are opposite rays

1 and 3 are vertical angles 2 and 4 are vertical angles (Textbook, 44)

Practice Problems: 1. Name a pair of vertical angles. 2. If 1 is 57, and 2 is x. What is x? 3. What is the value of x?
