GEOMETRY Notes 1.4: Measure and Classify Angles
#1 and 2
#1) Find the midpoint of . Show the midpoint on the graph, and write the name and coordinates of the point.
#2) If C is the midpoint of , plot D on the graph. What are the coordinates of D?
#3) What is the midpoint of given P(-2, 3p) and Q(4n, p)?
b) Why would it be confusing to call this ray ?
#8) Sometimes you will not see the entire rays that make the angle sides-- for example, if the angle is part of a triangle. In the applet, lengthen and shorten the segment sides of the angle-- do longer sides mean a larger angle? Name this angle in 3 different ways.
#10) Write an equation involving the angles in the applet.
