# Vertical and Linear Angles

Upright and linear angles

Note: Vertical angles are the "opposite angles" formed by two intersecting lines. To begin with, a linear pair of angles is a pair of adjacent angles. Two <'s that are additionally _______________ form a linear pair. Vertical angles ______ ______ have a common complement.

Search for vertical angle pairs and linear angle pairs.

## 8th Class Lesson Vertical Angles and Linear Pairs

At the beginning I projected the Launch Vertical Angles image onto the SmartBoard and told the classmates to find similar crossings on the Manhattan, NYC part maps. Calling on the voluntary workers to go upstairs and encircle an intersection similar to the ones in Inset_Images 1 to 7 on the card.

There are three of these pictures showing angular couples that were examined in the last two lesson. The alternative itinerary is printed and the picture is sent to them. Having encircled and renumbered seven similar crossings, I ask the classmates if anyone has any reservations. When there are none, I ask the form to indicate which intersection points contain angles made up of two straight line and one transverse, and which contain only two straight line.

When necessary, I indicate to the pupils that they would like to indicate which specific angular pairings are shown in Figures 2, 5 and 6. Speaking to the classmates, in this unit we will look at angles that consist of two crossing lineages and get to know their name and attributes.
