Polygons for $100
If you extend a side of this polygon, the line would pass through the interior of the polygon
Concave Polygon
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 $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 $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
