#7 Perpendicular Line Through a Collinear Point
Step-by-Step Instructions
a. Place D between A and C.
b. Create a circle with radius length CD and center the circle at C.
c. Place point E where the circle intersects segment CB.
d. Create a circle with a radius length of AC and center this circle at D.
e. Make a copy of the circle with radius length AC and center it at E.
f. Show the points of intersection for the two congruent circles, call them F and G.
g. Draw line FG.
h. Change the color/thickness of the line.
i. Use the angle tool to verify that the line is perpendicular to segment AB.
