True or False?
All quadrilaterals are polygons.
True - a polygon is any 2D shape formed with straight lines. This means that all quadrilaterals are polygons.

What type of triangle is this?
30 degrees, 30 degrees, 120 degrees
Obtuse Triangle
200
A quadrilateral with 2 pairs of parallel sides, 4 right angles, but the sides are not equal.
Rectangle
200
True or False?
All polygons are quadrilaterals.
False - A polygon is sometimes a square. Polygons can be other shapes such as triangles, pentagons, hexagons, heptagons, octagons, nonagons, or decagons.
200
Is the following figure a polygon?
Yes or no?
Yes - a polygon is any closed shape with straight lines.
200
When you see a square in the corner of a shape, what type of angle does that represent?
A right angle - 90 degrees
200
True or False: When graphing ordered pairs, the X coordinate tells you how many spaces to move up or down.
FALSE!! The x coordinate tells you how many spaces to move on the X-axis (left or right).
300
A quadrilateral with 1 pair of parallel sides.
Trapezoid
300
True or False?
A rectangle is always a square.
False - a rectangle is sometimes a square. Sometimes a rectangle does not have 4 equal sides.
300
How many sides does a hexagon have?
6
300
How many degrees does this angle appear to be?
A) 135 degrees
B) 90 degrees
C) 45 degrees
C) 45 degrees because it is smaller than 90!
300
Name the ordered pair (x,y) that represents: 3 spaces to the right of zero, and 5 spaces up.
(3, 5) The order matters!!
400
A quadrilateral with 2 pairs of parallel sides, 2 pairs of equal sides (Ex: 4cm, 6cm, 4cm, 6cm), and no right angles.
parallelogram (a rhombus needs ALL 4 equal sides... nut just 2 pairs)
400
True or False?
A circle is a polygon.
False - a polygon is any closed shape with straight lines.
400
What how many right angles does a rectangle have?
4
400
A square has how many right angles?
4
400
A four sided, closed shape belongs to this family of shapes.
Quadrilaterals
500
A quadrilateral with 2 pairs of parallel sides and 4 equal sides, but no right angles.
Rhombus
500
All squares are rectangles.
True - If a quadrilateral has 4 right angles it is automatically a rectangle. A square is a type of rectangle.
500
What is the difference between a REGULAR polygon and an IRREGULAR polygon?
All the sides of a REGULAR polygon are the same length. However, in an IRREGULAR polygon, all the sides are not equal.
500
Every triangle has AT LEAST how many acute angles?
2!!! (only an equilateral triangle has 3 acute angles)
