(upbeat music) - Good morning, my magnificent mathematicians.

Welcome to the Arkansas PBS Rise and Shine Shape Awards.

I'm so excited to be with you this morning.

We are going to have so much fun today learning more about math and growing our brains.

Today, we are going to celebrate different shapes and highlight how some of them share attributes or characteristics.

Before we get started, let's check your mastery of quadrilaterals.

So quadrilaterals are shapes with exactly four sides.

Now, today we have five magnificent quadrilaterals and I need you to help me announce their awards.

Let's start with our first award.

This quadrilateral is winning our VIP award.

It has four right angles, all four sides are congruent, and opposite sides are parallel.

Let's see who our winner is.

Congratulations to Suk Square.

Okay, let's move on to our second award.

The next quadrilateral is winning the award for the sharpest in the bunch.

This quadrilateral has four sides.

Both pairs of sides are parallel to each other, which means the lines never intersect.

They also have four right angles.

And on top of all of this, this quadrilateral offers us some variety.

The four sides are not the same length, meaning they're not congruent like our first winner.

With its two different side lengths, this winner has to be Rayanna Rectangle.

Great job, Rayanna.

(crowd cheering) For our third award, I get to present to a very special quadrilateral.

It's the warm and welcoming award.

This quadrilateral has at least one pair of parallel sides, so it welcomes other quadrilaterals to its friend circle.

Now, sometimes the other sides are not parallel, meaning that if we extended those lines, they would eventually intersect.

This quadrilateral doesn't care about being right all the time.

In fact, you may never see them flexing any right angles.

And the winner is (drum roll) Trenchant Trapazoid.

Congratulations, Trenchant.

Our fourth award for the day is the lean on me award.

This quadrilateral always stays in line with both pairs of sides parallel, but the lengths of the sides are different, meaning they're not congruent.

Also, there aren't any square corners.

If you run into this winner and need a friend, you are guaranteed to be able to lean on them.

This winner is (drum roll) Paola Parallelogram.

Congratulations, Paola.

(crowd cheering) Okay, it's time for our final award.

This is the equality award.

This quadrilateral also keeps it straight with two pairs of parallel sides, but they're a little extra because all four sides are equal lengths.

Also, there are no right angles.

Our winner is Riatta Rombus.

Great job, Riatta.

Great job helping me reveal the winners.

They are all so worthy of the awards they received.

Okay, I have a challenge for you.

When you think about a trapezoid, the most common example we see looks like this, but I want to challenge you to think about a different shape.

Is this shape a trapezoid?

Let's think about the characteristics of a trapezoid.

Is this a quadrilateral?

Does it have four sides?

Yes.

Does it have at least one set of parallel sides?

Yes.

It also has two right angles.

So is this a trapezoid?

Yes, it is.

It meets the qualifications.

A quadrilateral is a trapezoid as long as it has at least one set of parallel sides.

The right angles actually make it a really special trapezoid called a right trapezoid.

Now, these are also trapezoids.

The square.

It has four sides with at least one pair of parallel sides.

The rectangle, it's a trapezoid too.

Now let's talk about the rhombus and the parallelogram.

Do they have four sides with at least one pair of parallel sides?

Yes, they do.

Sometimes, when shapes share attributes or characteristics, it's almost like they all have the same parent shape.

So all of these shapes are trapezoids.

They just have other special features that make them unique.

Okay, that's all for today.

I hope you enjoyed our awards ceremony and that the review kind of helps you remember important facts about quadrilaterals.

And I hope that you have an amazing day.

I'll see you next time on Rise and Shine.

Bye.
