Angles are formed by intersection of non-collinear lines, rays and planes.
<u>Part A</u>
<u>1. Contradictory Example</u>

<u>2. A more accurate definition</u>
A more accurate definition is that:
An angle is formed at the intersection of two non-collinear rays that have the same endpoint
<u>Part B</u>
<u>Example of an undefined term</u>
Undefined terms do not have a formal definition; an example is the plane.
A plane pertains to angles because it determines the parameter to be measured.
