Prime purpose of this lecture is to present on Angle. Angle is the space (usually measured in degrees) between two intersecting lines or surfaces at or close to the point where they meet. When you “name” an angle. The vertex/angle “letter/number” goes in the center of the label. This lecture briefly describe four types of angles: acute angle-an angle between 0 and 90 degrees; right angle-an 90 degree angle; obtuse angle-an angle between 90 and 180 degrees and straight angle-a 180 degree angle.
