Select the correct definition.

Transversal

• a line with an endpoint and continues in the other direction.

•  two angles that intersect to form right angles.

• angles that are in the same position on two parallel lines in relation to a transversal.

• a line that intersects two or more other lines.

What is a Vertex?

• Two rays.

• When two arrows go on forever.

• The place where lines or segments meet.

  (Vertices - more than one vertex)

• The middle.

Select the correct definition.

Parallel Lines

•  a figure formed by two rays with a common endpoint.

• two lines that intersect to form right angles.

• two lines in the same plane that will never intersect or cross.

• angles that share a ray.
