Week 1

Polygon - A closed plane figure made up of at least 3 line segments that are joined together. (Triangles, Squares, etc...)
Parallelogram - A quadrilateral with opposite sides parallel.
Quadrilateral - A polygon with four sides (square, rectangle)


Week 2

Rhombus- a parallelogram with four equal sides
Trapezoid- a quadrilateral that has exactly one set of parallel sides


Week 3

Hexagon- A polygon with 6 sides
Octagon- a polygon with 8 sides
Congruent - figures or angles that have the same size and shape

Week 4

Reflection - a transformation resulting from a flip
Rotation - A transformation in which a figure is rotated through a given angle, about a point
Translation - a transformation, or change in position, resulting from a slide with no turn

Week 5

Acute angle - a positive angle measuring less than 90 degrees
Obtuse angle - an angle whose measure is greater than 90 degrees
Right angle - an angle whose measure is 90 degrees
Straight angle - an angle that measure 180 degrees
