3. Angle
An angle is formed by 2 rays with the same endpoint.

4. Constructing Congruent Angles
1. Construct a ray
2. with the compass on the vertex, draw an arc.
3. Draw the same arc on the ray.
4. Open the compass to length arc. Put the compass on intersection and draw an arc.
5. Draw ray.

5. Constructing Angle Bisectors
Step 1: Place the compasses’ point on the angle’s vertex and draw an arc.
Step 2: Place the compass on the point where the arc crosses a leg and draw an arc. Repeat.
Step 3: Draw a line from the vertex to the intersection point.
