Exercise 1 Page 957

To reflect a figure in a given line, we need to follow a few steps.

1. Draw a line through each vertex that is perpendicular to the given line.
2. Measure the distance from one point to the line. Then locate the reflected point the same distance from the given line on the opposite side.
3. Repeat step 2 to locate the reflected points of the remaining vertices to form the reflected image.

Note that point B is on the opposite side of line m from points C, D, and A. Therefore, B' will be on the opposite side of m compared to the rest of the reflected points. Let's draw the reflected image!

Step 1

We will begin by drawing a line through each vertex that is perpendicular to m.

Step 2

Now, let's measure the distance between point A and line m using a ruler.

Next, we can locate A' at the same distance from line m on the opposite side.

Step 3

Now, we will repeat step 2 to locate points B', C' and D'. First, we measure the distances between the remaining points, B, C, D, and line m. Then, we locate B', C' and D' at the same distance from m on the opposite side.

Finally, we can connect the points to form the reflected image.
