Unit 1 Day 4: Angle Pairs

Objective: Students will identify and use special pairs of angles

Adjacent Angles

Two angles that lie in the same plane and have a common vertex and a common side but no common interior points
Two angles that are next to each other

Linear Pair

A pair of adjacent angles with noncommon sides that are opposite rays
Notice that the first 4 letters of linear spell line, so a linear pair forms a line.

Multiple Choice

Find the value of x in the diagram so that the angles form a linear pair

118

Multiple Choice

x = 118

x = 108

x = 28

x = 58

x = 62

Poll

I can identify if two angles are complementary, supplementary, or vertical

Absolutely!

If I had more practice I could

I don't really know how to do this

I don't even know what you're talking about!

Poll

What is the most confusing part of this section?

Knowing the type of angles

Setting up the equations

Solving the equations

Nothing is difficult

I haven't been here so...everything

Two angles that add up to 90^o

Two angles that add up to 180^o

When you have two two lines that cross, the angles across from each other
