Which of the following pairs of angles proves that two lines are parallel?

• Linear pair

• Alternate interior angles

• Vertical angles

• Complementary angles

If two lines are cut by a transversal and the corresponding angles are congruent, what can you conclude?

• The lines are skew.

• The lines are parallel.

• The lines are perpendicular.

• The lines form a triangle.

Which of the following is NOT a valid method to prove two lines parallel?

• Corresponding angles are congruent.

• Same-side interior angles are supplementary.

• Alternate interior angles are congruent.

• Adjacent angles are complementary.

What does the Converse of the Alternate Interior Angles Theorem state?

• Parallel lines form alternate interior angles.

• Alternate interior angles are always equal.

• If alternate interior angles are congruent, then the lines are parallel.

• If alternate exterior angles are congruent, then the lines are parallel.

How is the distance from a point to a line determined?

• By measuring along the x-axis.

• By finding the shortest perpendicular segment from the point to the line.

• By using the slope of the line.

• By measuring any segment connecting the point to the line.

A line is perpendicular to another line if:

• The slopes are equal.

• The slopes are negative reciprocals.

• The angles they form are obtuse.

• The slopes are identical.

If a line has a slope of , what is the slope of a line perpendicular to it?

• -4/3

• 4/3

• -3/4

• ¾

Which of the following relationships is true for perpendicular lines?

• Scalene

• Isosceles

• Acute

• Right

What type of triangle has one angle measuring 90°?

• Acute triangle
