Constructions

Construct the 3 perpendicular bisectors of:

1. an acute triangle
2. an obtuse triangle
3. a right triangle

Now construct the circumscribed circles of each of the above triangles.

Construct the 3 angle bisectors of:

4. an acute triangle

5. an obtuse triangle

6. a right triangle

The 3 angle bisectors of a triangle intersect at one point callede the incenter.

For numbers 4-6, pick the longest side of each triangle. Use your knowledge of how to construct a perpendicular through a point NOT on the line to construct a perpendicular to your longest side through the incenter.

Good luck! See you tomorrow! Remember, tomorrow is early release which means we end at 12:40.

P.S. make sure you KNOW the definitions for median and altitude BEFORE you walk into my class tomorrow. I do not have time for you to be confused! KNOW them like the back of your hand!
