Medians and Altitudes

Front

What is an altitude in a triangle?

Back

An altitude is a line segment from a vertex of the triangle perpendicular to the line containing the opposite side.

Front

What is a median in a triangle?

Back

A median is a line segment from a vertex of the triangle to the midpoint of the opposite side.

Front

What is the relationship between altitudes and angles in a triangle?

Back

Altitudes create right angles (90 degrees) with the base of the triangle.

What is the formula to find the length of a median in a triangle?

Back

The length of a median can be calculated using the formula: m_a = 1/2 * sqrt(2b^2 + 2c^2 - a^2), where a, b, and c are the lengths of the sides.
