2. What is a construction?
A construction is a method of creating geometric figures without the benefit of measuring tools.
We only use a pencil, straightedge, and a compass.

3. Construction #1: Copying a Line Segment
Given a line segment of a certain length, I want to copy that line segment and create a congruent segment without using a ruler.
How to copy a segment:
Now complete the practice on your Lab

4. Construction #2: Construct a Perpendicular Bisector
A perpendicular bisector is a line that BISECTS a segment at a RIGHT angle.
To create a perpendicular bisector:
Complete the 2 practice bisectors on your page.

5. Construction #3: Copying an Angle
Similar to copying a segment, sometimes we want to copy an angle to create a new one that is CONGRUENT to the first.
How to copy an angle:
Copy the two angles in the practice

6. Construction #4: Bisecting an Angle
An angle bisector splits an angle in half into TWO congruent angles that are half the measure of the original angle.
How to bisect an Angle: M
Bisect the two angles in the practice
