Acute angle - An acute angle is an angle that measures less than 90 degrees. A triangle formed by all angles measuring less than 90˚ is also known as an acute triangle.

Obtuse angle - An obtuse angle has a measurement greater than 90 degrees but less than 180 degrees.

intersecting line - When two or more lines cross each other in a plane, they are called intersecting lines.

Triangle - A triangle is a polygon with three edges and three vertices.
