0
Name 2 characteristics of a hexagon
It has 6 sides, all sides are equal
If a quadrilateral shape has 4 sides, are ALL quadrilaterals a parallelogram? Explain why or why not.
No, it's not always a parallelogram because it doesn't always have 2 sets of parallel lines.
How many angles does a pentagon have?

A shape that has 3 or more sides.
Write and draw the name of the shape with 4 sides and 4 angles
A square, rhombus, parallelogram, trapezoid, or rectangle.
What is a quadrilateral?
A parallelogram has 2 sets of congruent sides, 2 sets of parallel sides, and 4 sides. Is a pentagon a parallelogram? Why or why not?
No, a pentagon is a five-sided polygon, and there are only four sides in a parallelogram.
How many angles does a hexagon have?
6

hexagon
Describe in a complete sentence what a rectangle is
It has four right angles, but the sides do not have to be the same length.
Is a rhombus always a square? Explain why
No, because a square has 90 degree angles.
Square facts: 4 congruent sides, 4 right angles, 2 sets of parallel sides. Is a rectangle always a square? Why or why not?
No, a rectangle does not always have 4 equal sides.
How many more angles does a hexagon have than a pentagon?
This polygon has 4 sides and 4 vertices (ex. trapezoid, rhombus...)
