Unit 1 Day 4: Angle Pairs

Objective: Students will identify and use special pairs of angles

Intersecting lines

Lines that cross or will cross if they are extended.

Multiple Choice

What do we call lines that cross?

Parallel

Perpendicular

Intersecting

Parallel Lines

Parallel lines will never intersect

Multiple Choice

What do we call lines that will never intersect?

Parallel

Perpendicular

Intersecting

Perpendicular lines

Lines that intersect and create right angles at the point of intersection.

Multiple Choice

What do we call lines that intersect and form 90 degree angles?

Parallel

Perpendicular

Intersecting

Multiple Choice

Are these perpendicular lines?

Yes

Multiple Select

I know these are perpendicular lines because. They form a ___ where they cross.

right angle

90 degree angle

acute angle

obtuse angle

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

Multiple Select

Which for the following adjacent angles? (Check ALL that apply)

$\angle UEN$ and $\angle SEU$

$\angle UEN$ and $\angle NET$

$\angle NEU$ and $\angle NET$

$\angle UES$ and $\angle TEN$

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.
Angles that form a linear pair are supplementary.

Multiple Choice
