Incenter- Part 1

The incenter is the point at which all the ______ of a triangle meet.

• altitudes

• angle bisectors

• medians

• perpendicular bisectors

What is the special property for incenters?

• The distance from the incenter to the sides will all be the same.

• The distance from the incenter to the vertices will all be the same.

• The incenter is always at the center of the triangle.

• The incenter is always outside the triangle.

• 8

• 16

• 17

• 34
