Provide an appropriate response.Use a compass and straightedge to construct an angle of 22.5°.
What will be an ideal response?
Answers will vary. A sample correct response would be as follows.
Start with a point P on a line, and construct a 90° angle (i.e. a perpendicular to the line) at P. Then bisect this angle to construct a 45° angle, and further bisect this 45° angle to construct a 22.5° angle.
