Presentation transcript:

 Take out your homework  Ray SW bisects <TSR, <TSW=x+2, and <WSR=2x-3. Find the value of x and <TSR.

 Angles can also be classified based on their relationship to other angles  Objective: Identify and use adjacent angles, vertical angles, complementary angles, supplementary angles, and linear pairs of angles.

 Adjacent Angles  They are angles in the same plane that have common vertex and a common side, but one common interior points. Linear Pairs  They are adjacent angles whose noncommon sides are opposite rays  Vertical Angles They are two nonadjacent angles formed by two intersecting lines.

A B C D E F G H Adjacent angles: <HBA and <ABC <IAJ and <JAK K J I Vertical Angles: <HBA and <CBG Linear pair: <CDA and <FDA

 Supplementary Angles They are two angles that have the sum of 180 ⁰  Complimentary Angles The are two angles that have the sum of 90 ⁰

1. If <PQS and <SQR are supplementary, find m<SQT and m<TQR. 6 x - 15 x + 78

2. If <OPN and <MPN are complimentary, what are their angle measurements? N O P M (2x - 1)⁰ (4x + 23)⁰
