00:00:03.400 --> 00:00:09.160
On the grid, there are three points joined by two lines.
00:00:09.160 --> 00:00:14.480
Lara plots another point on the grid at minus one, two.
00:00:16.840 --> 00:00:19.400
She joins the points to make a quadrilateral.
00:00:20.560 --> 00:00:22.960
Complete Lara’s quadrilateral on the grid.
00:00:23.480 --> 00:00:26.080
Use a ruler.
00:00:26.080 --> 00:00:31.960
Then Lara translates the quadrilateral four squares to the right.
00:00:31.960 --> 00:00:35.480
Draw the quadrilateral in its new position on the grid.
00:00:36.720 --> 00:00:38.800
Let’s start with the first part of the question.
00:00:40.120 --> 00:00:46.000
We need to plot another point on the grid at minus one or negative one, two.
00:00:47.240 --> 00:00:57.840
So our point needs to be at negative one on the 𝑥-axis and two on the 𝑦, which is this point right here, marked in pink.
00:00:59.240 --> 00:01:03.440
Next, we have to join the points to make a quadrilateral.
00:01:04.600 --> 00:01:09.000
“Quad” means four, and “lateral” means sided.
00:01:09.520 --> 00:01:11.880
So we have to make a four-sided shape.
00:01:13.200 --> 00:01:15.880
And we need to remember to use a ruler.
00:01:18.280 --> 00:01:21.000
So first, we can join these two points.
00:01:22.960 --> 00:01:27.520
And then we can join the next two points.
00:01:27.520 --> 00:01:30.880
We’ve drawn a quadrilateral, a four-sided shape.
00:01:32.480 --> 00:01:43.440
Next, we have to translate the quadrilateral four squares to the right and draw the quadrilateral in its new position on the grid.
00:01:44.720 --> 00:01:46.160
Let’s start with this point.
00:01:46.440 --> 00:01:50.240
We need to translate it four squares to the right.
00:01:51.680 --> 00:01:57.440
Now let’s move the second point four spaces to the right.
00:01:57.440 --> 00:01:59.360
Now let’s translate the third point.
00:02:00.480 --> 00:02:02.840
Now we have all of the new points.
00:02:03.200 --> 00:02:07.920
We just need to join them together to draw the quadrilateral in its new position.
00:02:09.400 --> 00:02:14.920
It’s really important that we remember to use a ruler to get really nice straight lines.
00:02:20.080 --> 00:02:22.160
We can join the final pair of points.
00:02:23.960 --> 00:02:26.960
And there we have the quadrilateral in its new position.
00:02:28.640 --> 00:02:35.280
We completed the first quadrilateral by drawing a point on the grid at negative one, two.
00:02:36.400 --> 00:02:40.160
Then we translated the quadrilateral four squares to the right.
