Geometric Constructions

The links below lead to instructional videos for each construction:

1. Constructing a 60° Angle

2. Constructing a 90° Angle (or, constructing a perpendicular line through a point on the line):

3. Bisecting an Angle(helpful when constructing 30° angles, 45° angles, etc., since these angles are half of the angles we worked with earlier)

4. Constructing a Parallel Line Through a Point

5. Constructing a Perpendicular Line Through a Point Off the Line
