A line that intersects two or more lines at different points
Two angles that occupy the
same position. (like “upper left corner”)
Two angles that lie between the two lines on opposite sides of the transversal.
Two angles that lie outside the two lines on opposite sides of the transversal.

2. 1. Transversal t intersects parallel lines m and n.
If , find the measures of the other
numbered angles. Explain your reasoning.
2. Find the value of x that makes lines m and n parallel.
