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 it lines up. x e t This angle is right and/or 90º. v er © M. Tallman

Acute Angle- an angle that is less than a right angle (less than 90º).

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 angle is smaller. x e t This angle is acute. v er © M. Tallman

Obtuse Angle- an angle that is greater than a right angle (greater than 90º).

Obtuse Angle- an angle that is greater than a right angle (greater than 90º). When you line up a piece of paper with the vertex of the angle, you can see that angle is larger. x e t This angle is abtuse. r e v © M. Tallman
