![]() ![]() (ii) Write the co-ordinates of A’ and B’. (i) Reflect A and B in the origin to get the images A’ and B’. Using a graph paper, plot the points A (6,4) and B (0,4). (ii) Point Q is reflected about the line y = 0 to get the image R. (i) The point P (2, – 4) is reflected about the line x = 0 to get the image Q. Write down the co-ordinates of the image of (5, – 4). The image of a point P under reflection on the X-axis is (5, – 2). Find the co-ordinates of the images of the following under reflection in the origin: (iv) A scalene triangle is reflected in its greatest side. (iii) An isosceles triangle is reflected in its unequal side. (ii) A right-angled triangle is reflected in its hypotenuse. ![]() ![]() (i) An isosceles right-angled triangle is reflected in its hypotenuse. Name the figure formed by a triangle and its reflection, when: If P’ has co-ordinates (3, – 4), evaluate a, b. The point P (a, b) is first reflected in the origin and then reflected on the Y-axis to p’. The triangle A(1, 2), B(4, 4) and C(3, 7) is first reflected in the line y = 0 onto triangle A’B’C’ and then triangle A’B’C’ is reflected in the origin onto triangle A”B”C”. A point is called an Invariant point with respect to a given line if and only if lies on the line.(ii) Change the sign of ordinate i.e., y-coordinate. The reflection of the point P(x, y) in the line x = a is the point P’ (-x+2a, y). Reflection of a point in a line parallel to y-axis.The reflection of the point P(x, y) in the line y = a is the point P(x, -y+2a). Reflection of a point in a line parallel to x-axis.(ii) Retain the ordinate i.e., y-coordinate. (i) Change the sign of abscissa i.e., x-coordinate.
