Classify a shape with 2 pairs of parallel sides + 4 right angles
Today we'll classify quadrilaterals — four-sided shapes — by looking at their parallel and perpendicular sides.
Here is a four-sided shape. Let's figure out what kind of quadrilateral it is.
Let's name the four sides A, B, C, and D so we can talk about them.
Look at sides A and C. They run in the same direction and would never meet — they are parallel.
Now sides B and D. They are also parallel to each other!
So this shape has TWO pairs of parallel sides.
Next, check the corners. This corner is a right angle — a perfect square corner.
In fact, all four corners are right angles. That means every pair of touching sides is perpendicular.
Two pairs of parallel sides AND four right angles. That makes this shape a rectangle!
A rectangle has 2 pairs of parallel sides and 4 right angles. Great work classifying!
Now you try. Name this shape from the list under the drawing. Which name is it?
