A quadrilateral with 4 equal sides and 4 right angles.

Square 


100

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.

100

What is the fewest number of sides needed to make a polygon?

3

100

True or False- all quadrilaterals have parallel lines

False- not all quadrilaterals have parallel lines.

100
The interior angles of a triangle add up to equal _________ degrees 

180

200

A quadrilateral with opposite sides the same length and 4 right angles.

Rectangle (or square because a square is always a 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

A triangle with an angle that is greater than 90 degrees, but less than 180 degrees 

 

Obtuse Triangle

200

True or false- parallel lines makes and x

False! Parallel lines never meet, they go one forever.

200

In a(n) ___________ triangle, all of their sides are equal and all of their angles are equal

Equilateral

300

A quadrilateral with at least 1 pair of parallel sides.

Trapezoid

Which statement is true?

A) A parallelogram has 4 right angles.
B) A square have equal sides.
C) A rhombus has 4 right angles.
D) A rectangle has only 4 equal sides.

B) A square have equal sides.

300

True or false: If c2 < a2+b2, the triangle will be classified as an obtuse triangle

False, it will be classified as an Acute Triangle 

400

A quadrilateral with 2 pairs of equal sides and no right angles.

Parallelogram

400

True or False?

A circle is a polygon.

False - a polygon is any closed shape with straight lines.

400

A triangle with three different side lengths.

How many ways different ways can you classify a triangle?

6 

500

A quadrilateral with 4 equal sides but no right angles.

Rhombus

500

True or false?

A rhombus is a square.

False - All squares have equal sides and right angles. A rhombus does not have right angles.

500
