Angles and their Properties
An angle is the angle formed by two rays that intersect at a single point. The angle is measured in degrees, minutes, and seconds.
Properties of angles:
The sum of the angles in a triangle is always 180 degrees.
The sum of the angles on the same side of a transversal (a line that intersects two or more rays) is equal.
Angles formed by intersecting rays are supplementary, meaning their sum is 180 degrees.
Angles formed by adjacent rays are congruent, meaning their measures are equal.
Complementary angles add up to 180 degrees.
Adjacent angles add up to 180 degrees
