3.1.4 Properties of Perpendicular Lines

Question 1

perpendicular bisector

Answer 1

(of a segment) is a line perpendicular to a segment at the segment’s midpoint

Question 2

distance from a point to a line

Answer 2

is the length of the perpendicular segment from the point to the line

Question 3

Linear Pair of Congruent Angles Postulate

Answer 3

If two intersecting lines form a linear pair of congruent angles, then the lines are perpendicular.

Question 4

Perpendicular Transversal Theorem

Answer 4

In a plane, if a transversal is perpendicular to one of two parallel lines, then it is perpendicular to the other line.

Question 5

Lines Perpendicular to the Same Line Theorem

Answer 5

If two coplanar lines are perpendicular to the same line, then the two lines are parallel to each other.
