Use graph paper for this question. Take 1 cm = 1 unit on both axes. Plot the points A(3, 0) and B(0, 4).
(i) Write down the coordinates of A1, the reflection of A in the y-axis.
(ii) Write down the coordinates of B1, the reflection of B in the x-axis.
(iii) Assign the special name to the quadrilateral ABA1B1.
(iv) If C is the midpoint is AB. Write down the coordinates of the point C1, the reflection of C in the origin.
(v) Assign the special name to quadrilateral ABC1B1.
Solution:
The coordinates of the mid-point of the line segment PQ are (1, -2). The coordinates of P are (-3, 2). Find the coordinates of Q.(1992)
Solution:
More Solutions:
- The reflection of the point P (-2, 3) in the x-axis is
- The reflection of the point P (1, -2) in the line y = -1 is
- The point P (4, -7) on reflection in x-axis is mapped onto P’.
