Relationships Within Triangles

What is the altitude of a triangle?

• A segment from a vertex of a triangle to the midpoint of the opposite side.

• The point of concurrency of the three medians of a triangle.

• The perpendicular segment from a vertex of a triangle to the opposite side or to the line that contains the opposite side.

• A segment that connects the midpoints of two sides of a triangle.
