The Case of the Missing Diagram
The following exercises are about $\triangle \mathrm{ABC}$, in which $\mathrm{AB}=8 \mathrm{cm}, \mathrm{AC}=10 \mathrm{cm},$ and $\mathrm{BC}=$$6 \mathrm{cm}$ Use your straightedge and compass to construct $\triangle \mathrm{ABC}$. Bisect $\& \mathrm{C}$ and label the point in which the bisector intersects $\overline{\mathrm{AB}} \mathrm{D}$

The Angle Bisector Theorem
Now you’ll look at how an angle bisector of a triangle divides the side opposite to the angle. Reopen GeoGebra, and complete each step below. Part A Construct a random triangle, , and construct the angle bisector of . The angle bisector divides the opposite side, , into two line segments. Mark the point where the angle bisector intersects , and label it D. To verify that you have bisected the angle, measure and and display the angle measures. Take a screenshot of your construction, save it, and insert the image below.
