Polygons for $100

If you extend a side of this polygon, the line would pass through the interior of the polygon

Concave Polygon

Polygons for $200

This polygon has all sides and all angles equal in measure.

Regular Polygon

Polygons for $300

This sum of the interior angles of this polygon is 720°

Hexagon

Vocabulary for $100

A statement that is accepted without further justification

Postulate

Vocabulary for $200

A one-dimensional object that extends without end in two directions

Line

Vocabulary for $300

A plane figure that is formed by three or more segments called sides. Each side intersects

exactly two other sides at each of its endpoints. Each endpoint is a vertex of this

figure

Polygon

Angles for $100

These angles share a common vertex, a common side, but no common interior points.

Adjacent Angles

Angles for $200

These non-adjacent angles are formed by the intersection of two lines and are congruent.

Vertical Angles

Angles for $300

These congruent angles are formed when parallel lines are cut by a transversal. This

particular pair exist between the two parallel lines.

Alternate Interior Angles

Triangles for $100

This triangle has NO two sides that are equal in length.

Scalene Triangle

Triangles for $200

This triangle has one angle that’s greater than 90° while the other two are both less than 90°.

Obtuse Triangle

Triangles for $300

These 5 postulates are what allow us to determine if two triangles are congruent.

S-S-S, S-A-S, A-S-A, A-A-S and H-L

Right Triangles & Trig for $200

This trigonometric ratio compares the opposite to the hypotenuse.

Sine

Right Triangles & Trig for $400

If you know the ratio of the adjacent and the hypotenuse, you can find the angle by using

this function

Inverse Cosine or Cos-1

Right Triangles & Trig for $600

Given the triangle,

the sine of R would equal the cosine of this angle

Angle P

Quadrilaterals for $200

This quadrilateral has opposite sides parallel, opposite sides congruent, opposite angles congruent, adjacent angles supplementary,

and diagonals that bisect each other

Parallelogram

Quadrilaterals for $400

This parallelogram has congruent diagonals but adjacent sides are NOT congruent

Rectangle

Quadrilaterals for $600

This parallelogram has diagonals that intersect at right angles, but adjacent angles do not

have to be congruent

Rhombus

Basics of Geometry for $200

If two lines intersect, this is where they’ll intersect.

A point

Basics of Geometry for $400

The union of two rays can be referred to as this shape or figure.

An angle

Basics of Geometry for $600

Two lines that don’t intersect are referred to as parallel if they’re in the same plane. This is what we call two lines that don’t intersect if

they’re in DIFFERENT planes.

Skew

Segments & Angles for $200

This is the word we use if we divide an object into two congruent parts

Bisect
