Bisect This
1. Estimate the location of a point D so that angle ABD is approximately congruent to angle CBD.
2. Use compass and straightedge tools to try to create a line that divides angle ABC into 2 congruent angles.
Take turns with your partner, drawing and bisecting other angles.
1. Have your partner create an angle for you below using 2 rays. Your partner should explain to you the steps to help you bisect it. Listen carefully to their explanation and follow their steps to bisect the angle.
2. Create an angle for your partner on their screen. Explain to your partner how each straightedge and compass move helps you to bisect it.
For each angle that your partner draws, listen carefully to their explanation. If you disagree, discuss your thinking and work to reach an agreement.
