## Unit 1 Lesson 4 Vertical Angles Exploration

This is an element of your Unit 1 Project and should be added to your Unit 1 Project portfolio after you answer the feedback on the assignment provided by your teacher.

## Essential Question:

• How can we use vertical angles to help build structures?

## Objectives:

• Write a theorem that can be used to solve problems involving vertical angles using the SPORT method.

• Solve problems involving vertical angles

## Part I: Specific Cases & Examples

Open the vertical angles GeoGebra applet on your laptop or iPad. Move the points D, E, and C around and notice how it changes the measures of all four angles. Record the measurements of the angles in 5 cases when it shows "Vertical Angles" on the screen and 5 cases where it does not show "Vertical Angles" on the screen. Include one screenshot of when you have vertical angles shown.
