Geometry Homework - Section 5.1Perpendicular Lines and Bisectors

Perpendicular lines are lines that intersect at a right angle (90 degrees).

The slope of a line that is perpendicular to a line with a slope of 2 is -1/2.

The midpoint M is given by M = ((x1 + x2)/2, (y1 + y2)/2).

The slope m is calculated as m = (y2 - y1) / (x2 - x1).

The equation of a line in point-slope form is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.

A point is equidistant from two figures if it is the same distance from both figures.

The slopes of two perpendicular lines are negative reciprocals of each other.

The slope of a line that is perpendicular to a line with a slope of -4 is 1/4.

A bisector is a line, segment, or ray that divides another segment or angle into two equal parts.

Two lines are parallel if they have the same slope and different y-intercepts.
