- Distance
- Distance Formula
- length, how far
- Phythagorean Theorem
- Midpoint
- Midpoint Formula
[(x1+x2)/2, (y1+y2)/2]
- Midpoint and endpoint are colinear. Slope
endpoint A to midpoint and midpoint to endpoint B
is the same
- Slope
- parallel lines
- Slope of two line
are the same
- y1=m1x+b1,
y2=m2x+b2
m1=m2
- Horizontal lines,
y = # are parallel
- Vertical lines,
x= # are parallel
- Perpendicular lines
- The product of the
slope of two lines is -1.
the slope of two lines
are opposite reciprical.
- A vertical line
and a vertical
line are
perpendicular,
x=# and y=#
- y1=m1x+b1,
y2=m2+b2,
m1xm2 =-1
