Is this a rectangle?

To help us decide if the shape is a rectangle, let’s think about what we know about rectangles. Rectangles have four straight sides. Let’s check if our shape has four straight sides. Here’s one straight side and another. The shape has three straight sides. But the fourth side is curved. So this is not a rectangle.

Rectangles also have four right angles. And this shape only has two. So the answer to the question is no. We know the shape isn’t a rectangle because rectangles have four straight sides and four right angles.

This shape only has three straight sides and it has one curved side. And it only has two right angles. This is not a rectangle.
