1. A connects a vertex of a triangle to the midpoint of the opposite side.
2. An is a segment from a vertex perpendicular to the opposite side.
3. The point where the three medians of a triangle intersect is called the .
4. A segment that divides an angle into two congruent angles is an .
5. Which special segment always passes through the midpoint of a side and is perpendicular to that side?
Median
Altitude
Angle Bisector
Perpendicular Bisector
6. The point of concurrency for the altitudes of a triangle is called the:
Centroid
Incenter
Circumcenter
Orthocenter
7. Draw a triangle and then draw one median, one altitude, and one angle bisector from different vertices. Label each segment.
8. The incenter is equidistant from the three sides of the triangle.
True
False
