What is the definition of an altitude in geometry?

Back

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

What is the difference between a median and an altitude?

Back

A median connects a vertex to the midpoint of the opposite side, while an altitude is perpendicular to the opposite side.

How do you find the measure of an angle in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees. To find an unknown angle, subtract the sum of the known angles from 180 degrees.
