Question

Activity on title Mirror image in co-ordinate geometry

Answer 1

Materials Required

Graph paper, pencil (coloured), eraser, ruler and mirror.

Procedure

Draw any figure on the graph paper in first quadrant (say, a figure of stairs).

For stairs, plot some points say, A(3,0), B(3,1), C(2,1), D(2,2), E(1,2), F(1,3), G(0,3) with coloured pencils.

join A, B, C, D, E, F, G as shown infig. (i).

Consider y-axis as a mirror.

Fold the graph along the y-axis to get the images of points A, B, C, D, E, F, G in second quadrant as A’, B’, C’, D’, E’, F’, G’ respectively as shown in fig. (i).

Join A’, B’, C’, D’, E’, F’, G’ we get the image of the stairs.

Note down the coordinates of image so formed and record them in observation Table 1.

Repeat the procedure for the same stairs with respect to x-axis i.e, to get image of the stairs taking x-axis as mirror.

Now, we will get image in fourth quadrant.

Note down the coordinates of image
