188.8.131.52 Use coordinate geometry to represent and analyze line segments and polygons, including determining lengths, midpoints and slopes of line segments.
a) I can determine the slope of a line.
b) I can determine the distance (length) between points
on a coordinate plane.
c) I can determine the midpoint of a segment given
coordinates of the endpoints.
d) I can use slopes and lengths to analyze polygons.
Please copy down these notes into your notebook for points.
