1. Which pair of angles are congruent when two parallel lines are cut by a transversal?
Consecutive interior angles
Same-side interior angles
Alternate interior angles
Vertical angles (only if transversal is perpendicular)
2. If angle 1 and angle 8 are alternate exterior angles, what is their relationship?
They are supplementary.
They are complementary.
They are congruent.
They are adjacent.
3. A line that intersects two or more lines is called a .
4. When two parallel lines are cut by a transversal, corresponding angles are .
5. In the diagram below, lines 'a' and 'b' are parallel, and line 't' is a transversal. If angle 1 measures 110°, find the measure of angle 5.
6. Alternate exterior angles are always supplementary.
True
False
7. If two lines are cut by a transversal and the consecutive interior angles are supplementary, then the lines are parallel.
True
False
8. Lines 'm' and 'n' are parallel. A transversal 'p' intersects them. If an interior angle on one side of the transversal measures (2x + 10)° and its corresponding exterior angle measures (3x - 20)°, find the value of x.
