- Bisecting an Angle: Dividing an angle into two equal parts using a compass.
- Perpendicular Bisector: Constructing a line perpendicular to a segment through its midpoint.
2. Constructing Angles
- 60° Angle: Using the radius of the circle as the chord length.
- 90° Angle: Bisecting the straight angle or using the 60°/120° method.
3. Triangle Constructions
- Given three sides (SSS).
- Given base, base angle, and sum/difference of other two sides.
- Given perimeter and base angles.
