What polygons were used to make this object?
squares - 4 congruent sides and 4 right angles in each
Polygons are quadrilaterals
Sometimes
What does congruent mean?
1 pair of parallel sides
Trapezoids
I am a closed shape with straight sides that don't cross. Who am I?
I am a polygon!
Name this polygon...
Hexagon
Trapezoids are paralellograms
Never
Parallelograms have 2 pairs of parallel sides.
Trapezoids only have 1 pair of parallel sides.
An angle that measures exactly 90 degrees and is a perfect corner is called a ________ angle.
Right angle
2 pairs of parallel sides
sometimes has right angles and sometimes does not
Parallelograms
I have more sides than a quadrilateral, but fewer than a hexagon. Who am I?
I am a pentagon!
Name this quadrilateral...
Trapezoid (only one pair of parallel sides)
Rectangles are parallelograms
Always
What are the 3 rules that a shape must follow to be considered a polygon?
1. Closed Shape
2. Straight Sides - NO Curves
3. No intersecting lines
2 pairs of parallel sides
4 right angles
All sides are congruent
I have four sides that are always the same,
my four right angles should help you know my name!
Who am I?
I am a square!
A 5 sided polygon is called a ______________.
Pentagon
A square can also be considered a rectangle.
Always - because it has 2 pairs of parallel sides and 4 right angles
What do we call the corner point where two or more lines or edges meet?
Vertex
4 congruent sides
0 right angles
I am a shape that has two pairs of parallel sides. Sometimes I have right angles and sometimes I don't. What shape am I?
Which shape below is not a polygon? Explain your reasoning.
Shape A is not a polygon because its sides intersect.
A rectangle can also be called a square.
Never - while they are both parallelograms, a rectangle does not have 4 equal or congruent sides. Squares do.
What does parallel mean?
Parallel lines are lines that never cross or intersect, even when they are extended.
2 pairs of parallel sides with 4 right angles
Rectangle or a Square
Sometimes I feel like I just don't belong.
I have 4 sides and sometimes a couple of them are long. I want to be in that special parallelogram club but they just keep insisting I break their rules. Who am I and why am I singing the blues?
I am a trapezoid and I can't be a parallelogram because I have only one pair of parallel sides.
