00:00:01.120 --> 00:00:03.860
Which shape has four corners?
00:00:05.570 --> 00:00:11.030
Before we answer that question, we need to think about what the word “corners” means.
00:00:15.510 --> 00:00:19.690
A corner is the place where two lines meet.
00:00:21.750 --> 00:00:23.820
Let’s look at an example of a corner.
00:00:25.630 --> 00:00:30.580
In this hexagon, two lines are meeting and forming a corner.
00:00:31.950 --> 00:00:33.680
Here is one corner.
00:00:35.420 --> 00:00:43.510
If we look at all the places two lines connect in a hexagon, we’ll know how many corners a hexagon has.
00:00:45.110 --> 00:00:47.220
We already found our first corner.
00:00:48.290 --> 00:00:56.780
Here’s a second corner, a third corner, a fourth corner, and a fifth and sixth corner.
00:00:58.670 --> 00:01:01.300
Our hexagon has six corners.
00:01:02.710 --> 00:01:08.800
Let’s follow the same procedure to find out how many corners the rectangle and the pentagon have.
00:01:10.870 --> 00:01:23.810
If a corner is a place where two lines meet, here is the first corner of a rectangle, the second corner, corner number three, and corner number four.
00:01:25.180 --> 00:01:27.450
A rectangle has four corners.
00:01:28.540 --> 00:01:43.370
Let’s take a look at the pentagon: one, two, three, four, and five.
00:01:44.610 --> 00:01:46.960
The pentagon has five corners.
00:01:48.260 --> 00:01:53.070
Our question is asking which shape has four corners.
00:01:53.570 --> 00:01:56.680
Only one of these three shapes has four corners.
00:01:58.160 --> 00:01:59.830
And that is the rectangle.
00:02:02.650 --> 00:02:07.930
The four sides of this rectangle meet to form four corners.
