When you line up a piece of paper with the vertex of the angle, you can see that it lines up.

This angle is right and/or 90º.

Right Angle- an angle formed when two perpendicular lines

meet or cross.

When you line up a piece of paper with the vertex of the angle, you can see that that angle is smaller.

This angle is acute.

Acute Angle- an angle that is less than a right angle (less

than 90º).

When you line up a piece of paper with the vertex of the angle, you can see that that angle is larger.

This angle is abtuse.

Obtuse Angle- an angle that is greater than a right angle (greater

than 90º).
