Math Assignment Reflection 1. Use graph paper for this question. (Take 2 cm = 1 unit along the both x and y axis.) Plot the points O (0, 0), A (- 4, 4), B (- 3, 0) and C (0, - 3) i. ii. iii. Reflect points A and B on the y axis and name them A and B respectively. Write down their coordinates. Name the figure OABCB A . State the line of symmetry of this figure. 2. Use graph paper for this question. (Take 2 cm = 1 unit along the both x and y axis.) i. ii. iii. iv. Plot the points A (-4 , 2) and B (2, 4) A is the image of A when reflected in the Y axis. Plot in on the graph paper and write the co ordinates of A . B is the image of B when reflected in the line AA . Write the co ordinates of B . Write the geometric name of the figure ABA B . 3. Using graph paper and taking 1 cm=1 unit along both x-axis and y-axis. i. ii. iii. iv. v. Plot the points A ( 4, 4) and B (2, 2) Reflect A and B in the origin to get images A and B respectively. Write down the co-ordinates of A and B . Give the geometrical name for the figure ABA B Draw and name its lines of symmetry. 4. Using a graph paper, plot the points A (6, 4) and B (0, 4) i. ii. iii. iv. Reflect A and B in the origin to get the images A and B . Write the co ordinates of A and B . State the geometrical name for the figure ABA B . Find its perimeter and area. 5. Use graph paper for this question The point P (5, 3) was reflected in the origin to get the image P . i. Write down the co ordinate of P .
