Unit 1: Lesson 4 Constructing Equilateral Triangles

1. ) I Notice. I Wonder?

Below is a picture of a Geometric Construction. Identify 3 things that you Notice and 2 things that you wonder.

2. ) Spot the Equilaterals

Use straightedge and compass moves to construct at least 2 equilateral triangles.

Spot the Equilaterals

3.) Creating Perpendicular Lines

Directions: Use a straightedge and compass to construct a line perpendicular to L, that goes through C.

Challenge #1:

Create a line that is (perfectly) Perpendicular to Line AB.

Challenge #2 "Stuck in a Circle"

Use Straightedge and Compass moves to create an Equilateral Triangle inscribed in this circle. Use the polygon tool to create it, once you have constructed the position of your verticies.
