In this lesson, we will look at constructing different angles and shapes using compasses
- A 90° angle can be obtained by constructing a perpendicular bisector.
- A 45° angle can be obtained by bisecting a 90° angle.
- A 22.5° angle can be obtained by bisecting a 45° angle.
- A 60° angle can be obtained by constructing an equilateral triangle.
- A 30° angle can be obtained by bisecting a 60° angle.
- A 15° angle can be obtained by bisecting a 30° angle.
Example:
The figure shows a point A on a straight line. Construct an angle of 45° at point A.
Solution:
Construct a 90° angle, and then construct an angle bisector to obtain a 45° angle.
