Altitude of a triangle

Describe the altitude of a triangle.

• The altitude is the angle formed by two sides of the triangle.
• The altitude is the area of the triangle divided by the base length.
• The altitude is the length of the longest side of the triangle.
• The altitude of a triangle is the perpendicular distance from a vertex to the line containing the opposite side.
