Ava Oliver, on November 3rd, 2017 at 10:29 am Said:where is the quarter?

Here is the quarter of the square.

How do you know its a square?

Because it’s got a 90 Degree angle.

So? A rectangle has 90 Degree angles.

But a rectangle is much longer than a square.

That doesn’t make sense.

I think it looks like a square.

But, how?

Because it has equal sides and equal angles

I am now convinced…

ella stephanie, on November 3rd, 2017 at 10:38 am Said:First I fold the square into four pieces. Then a quarter is one of the squares, I know this because if you do a pizza and you cut it in four slices.You know 1 of the slices is going to be a quarter, Because all of the sides are going to be even and there is a 90 degree angle.

ella stephanie, on November 3rd, 2017 at 10:50 am Said:First I folded the square into four triangles,then a quarter is one of the triangles.I know this because if you do a box and in the middle basically its a 90 degeree angle and its has three sides witch equals a quarter.

Ava Oliver, on November 3rd, 2017 at 11:00 am Said:How is that a quarter of a square?

I folded a triangle and halved it. When I opened it up it was a quarter of a square. Just in a different way.

But how do you know it’s a triangle?

It has 3 sides and is a right angled isosceles.

How do you know that?

Because a right angle isosceles has a right angle and two equal sides.

I am now convinced

But a rectangle has 90 Degree angles.
