Draw right, acute, and obtuse angles


Drag the vertex of the angle to place the vertex at point A.
Drag another point on the angle to make one of the rays go through point B.
Make the other ray go through one of the unlabeled black points to create a right angle.
The arc symbol near the vertex will show the right angle symbol when the angle is correct.
This is a right angle because its measure is
90, degree.
