polygon
Any closed figure bounded by three or more segments that only intersect at
their endpoints. The segments are called the sides, and the endpoints are
called the vertices of the polygon.
consecutive vertices
The endpoints of one side of a polygon.

The purpose of this review is to acquaint you with the major concepts that appear on the first semester exam
for the course Geometry. This review does not attempt to cover all the topics you will be tested o

AREA AND VOLUME
AREA OF TRAPEZOIDS
This lesson will focus on finding the area of a trapezoid. You will find that the terminology is very similar to
the previous lessons.
Recall that a trapezoid is a quadrilateral with exactly one pair of p
GRAPHS OF ALGEBRAIC SENTENCES
A graph in a plane is a set of points. In a previous unit, we studied sets of points called loci. A locus is a set
of points that meet certain geometric conditions.
Locus
We often use the term graph for a set of points whose
SOLIDS: PRISMS
We deal with two common measurements related to solid geometric figures: the area of the surface and the
volume.
In finding volume, we need to use a new unit of measure. This unit of measure for volume is a cube that
measures one unit long,
TRANSVERSALS AND SPECIAL ANGLES
You need only to look around you in any room to see the many examples of parallel lines and planes. When
parallel lines are crossed with another line, special angles are formed. Basic properties of parallels, the

AND ANGLES
We will now use some of the statements about parallels to prove some useful theorems concerning triangles
and other polygons.

The union of three segments determined by three noncollinear points.

ANGLE RELATIONSHIP THEOREMS (2)
In this lesson, you will continue to work with theorems about angle relationships.
These theorems about angle relationships will help you to work with related angles.
