8.2 (Day 2) Finding the Incenter
DIRECTIONS:
Navigating Geoebra:
- Click on the purple TOOLS icon
to access the Geogebra tools. - You may have to click on "MORE" to see all the tools
- You can zoom in and out on the graph.
- Use the POLYGON
tool to plot your points and construct your triangle. - Use the ANGLE BISECTOR (AB)
tool to construct the AB's of the triangle's 3 sides. - Use the MOVE
tool to select the intersection of the three angle bisectors. This will tell you the coordinates of that point.
Example A: Find the Incenter of the triangle with points A(6,6) B(8,-4) C(-3,5).
Example A
What are the coordinates of the incenter from the triangle in Example A? (leave your answer as a decimal)
Example B- You Try! Find the Incenter of the triangle with points (2,-4), (4,6), and (8,-4).
Example B- You Try!
What are the coordinates of the incener from the triangle in Example B? (leave your answer as a decimal)
