Practice the questions given in the worksheet on reflection in yaxis. The questions are based on how to find the coordinates of the image of a point under reflection in yaxis.
1. Find the reflection of the following in yaxis.
(i) (3, 7)
(ii) (4, 6)
(iii) (5, 7)
(iv) (3, 5)
2. Draw a line segment MN where M (3, 4) and N (5, 7). Reflect it in yaxis and find images of M and N. write the coordinates of M' and N'.
3. Draw a triangle ABC such that A (2, 3); B (5, 6); C (2, 5) are reflected in the yaxis to get the ∆ A'B'C'. write the coordinates of A', B' and C'.
4. Find the reflection of the following point in yaxis.
(i) A (3, 0)
(ii) B (0, 5)
(iii) C (8, 2)
(iv) D (5, 1)
5. A parallelogram whose vertices are A (2, 5), B (5, 2), C (5, 4), D (2, 1) is reflected in yaxis to the parallelogram A'B'C'D'. Write the coordinates of the vertices of the parallelogram A'B'C'D'.
