Please help me with this questions down here I have a terrible teacher and these problems are hard.

Question

1. Non adjacent angles of two intersecting lines

2. Two adjacent angles for which the noncommon Rays form a straight line.

3. A quadrilater with one set of parallel sides

4. Two angles that share a common Ray and endpoint but no common interior points

Answer 1

I assume these are definitions of geometric figures !?!?

1) two intersecting lines form 4 angles; if the angles are not adjacent they must be opposite each other and are called vertical angles

 

2) if the non common rays of the two adjacent angles form a straight line then the two angles are supplementary angles and form a straight angle; also called a linear pair of angles

 

3) a quadrilateral with one set of parallel sides is called a trapezoid

 

4) two angles with a common ray and a common endpoint are called adjacent angles
