Which of the following describes an altitude of a triangle?

• A segment that passes through the middle of the triangle.
• A segment with endpoints at the vertex and midpoint of the opposite side.
• A segment that connects two midpoints of two sides.
• A segment that connects the vertex and the opposite side at 90 degrees. 

A line segment that joins the midpoints of two sides of a triangle, is parallel to the third side and its length is one-half the length of the third side.

• Perpendicular Bisector
• Angle Bisector
• Median
• Midsegment
