ANGLES

• An acute angle measures less than 90 degrees.
• A right angle is an angle that measures exactly 90 degrees.
• A straight angle is equal to 180 degrees.
• A Obtuse angle is more than 90 degrees but less than 180 degrees
• Complementary angles are two angles that sum up into 90 degrees
• Supplementary angles is two angles that sum up into 180 degrees
• Adjacent angles share the same vertex and one side. They share a side (ray) and they do not overlap
• Two intersecting lines from two pairs of opposite angles called Vertical Angles
