Ready to print
Start with a ready-made worksheet
State whether point P is interior, exterior or on the angle. The vertex and both rays belong to the angle.
Download the practice pages alone, or include a separate answer key or teacher model. Longer activities may use more than one page.
Customize this worksheetRead rays, not short segments
An angle continues along both rays. A point on either ray or at the shared vertex is on the angle.
Learning objective
What this activity builds
Recognize the interior, exterior and boundary of a non-reflex angle.
Worked example
Point P lies on one ray that forms an angle. Is P interior, exterior or on the angle?
On the angle.
The two boundary rays and their shared vertex are on the angle. Interior points lie strictly between the rays; other points are exterior.
Teaching notes
Make the practice count
- Find both rays and the common vertex first.
- Choose interior only when the point is strictly between the rays.
- A point on a boundary ray or at the vertex is on the angle.
