00:00:03.030 --> 00:00:04.720
Is this a rectangle?
00:00:06.240 --> 00:00:13.140
To help us decide if the shape is a rectangle, let’s think about what we know about rectangles.
00:00:14.160 --> 00:00:17.690
Rectangles have four straight sides.
00:00:18.680 --> 00:00:22.100
Let’s check if our shape has four straight sides.
00:00:23.240 --> 00:00:28.650
Here’s one straight side and another.
00:00:29.950 --> 00:00:32.300
The shape has three straight sides.
00:00:33.260 --> 00:00:35.900
But the fourth side is curved.
00:00:36.960 --> 00:00:39.540
So this is not a rectangle.
00:00:40.770 --> 00:00:43.880
Rectangles also have four right angles.
00:00:44.670 --> 00:00:47.090
And this shape only has two.
00:00:48.490 --> 00:00:50.420
So the answer to the question is no.
00:00:51.310 --> 00:00:59.420
We know the shape isn’t a rectangle because rectangles have four straight sides and four right angles.
00:01:00.400 --> 00:01:05.390
This shape only has three straight sides and it has one curved side.
00:01:06.320 --> 00:01:09.220
And it only has two right angles.
00:01:10.170 --> 00:01:12.420
This is not a rectangle.
