Chapter 6

Chapter Objective:

* Base and height are measurements that are used to find the area of a triangle.

Vocabulary:

Vertex - The point at which two line segments or rays meet to form an angle.

Side - Any one of the line segments that form a polygon.

Angle - An angle is formed by two rays with the same endpoint.

Base - The face or side on which an object lies. In a triangle, any one side can be the base.

Height - The perpendicular distance from the base to the opposite vertex.

Perpendicular - Lines that intersect to form FOUR right angles.

Area - The amount of surface covered; commonly measured is square units, such as square centimeters (cm²) or square inches (in²).
