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. vertex Right Angle- an angle formed when two perpendicular lines meet or cross.

© M. Tallman 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). vertex

© M. Tallman 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). vertex
