Geometry Chapter 5 Review

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

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

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.

A perpendicular bisector is a line that divides a segment into two equal parts at a 90-degree angle.

In a right triangle, one angle is 90 degrees, and the other two angles are complementary, meaning they add up to 90 degrees.

A bisector is a line or segment that divides an angle or segment into two equal parts.
