On the grid, there are 3 points joined by 2 lines. Lara plots another point on the grid at (−1, 2). She joins the points to make a quadrilateral. Complete Lara’s quadrilateral on the grid. Use a ruler. Then Lara translates the quadrilateral 4 squares to the right. Draw the quadrilateral in its new position on the grid.

On the grid, there are three points joined by two lines. Lara plots another point on the grid at minus one, two. She joins the points to make a quadrilateral. Complete Lara’s quadrilateral on the grid. Use a ruler. Then Lara translates the quadrilateral four squares to the right. Draw the quadrilateral in its new position on the grid.

Let’s start with the first part of the question. We need to plot another point on the grid at minus one or negative one, two. 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. Next, we have to join the points to make a quadrilateral. “Quad” means four, and “lateral” means sided. So we have to make a four-sided shape. And we need to remember to use a ruler.

So first, we can join these two points. And then we can join the next two points. We’ve drawn a quadrilateral, a four-sided shape. Next, we have to translate the quadrilateral four squares to the right and draw the quadrilateral in its new position on the grid. Let’s start with this point. We need to translate it four squares to the right. Now let’s move the second point four spaces to the right. Now let’s translate the third point. Now we have all of the new points. We just need to join them together to draw the quadrilateral in its new position.

It’s really important that we remember to use a ruler to get really nice straight lines. We can join the final pair of points. And there we have the quadrilateral in its new position. We completed the first quadrilateral by drawing a point on the grid at negative one, two. Then we translated the quadrilateral four squares to the right.
