Jason drew this polygon on dot paper.
There are _________ angles.
There are _________ sides.
There are 4 angles.
There are 4 sides.
Math Idea
A polygon is a closed plane figure with straight sides that are line segments.
Jason’s polygon has 2 right angles. They form square corners. You can use the corner of a sheet of paper to tell if an angle is a right angle. Draw boxes to show the right angles.
Look at Jason s polygon. How many pairs of sides are parallel?
Lines that appear to never cross or meet and are always the saine distance apart are parallel lines.
So, Jason’s polygon has ___________ pair of parallel sides.
Answer:
So, Jason’s polygon has 1 pair of parallel sides.
Classify Quadrilaterals: Quadrilaterals are named by their sides and their angles.

Explain why a square can also be named a rectangle or a rhombus.
Answer:
Explanation:
A square can be described as a rectangle because a square has 4 equal sides
and a rectangle has 2 parallel sides are equal
In rhombus 4 sides are equal so, A rhombus can also be called as a square
Every Square is a rectangle, but not every rectangle is a square.
A square is a special kind of closed figure with four straight sides and four right angles that also has sides that all have equal length. Therefore, we can conclude that: A Square is a special kind of rectangle
