Question

Write the co-ordinates of the point that is the mirror image of the point at a

distance of 3 units from x axis and 5 units from y axis, in the second

quadrant. The mirror is making an angle of 45 degrees with the positive

side of x axis and facing upward.​

Answer 1

Step-by-step explanation:

Write down the coordinates of each of the points A, B, C, D, E shown below:

ANSWER:

Draw perpendicular AL, BM, CN, DP and EQ on the X-axis.

(i) Distance of A from the Y-axis = OL = -6 units

Distance of A from the X-axis = AL = 5 units

Hence, the coordinates of A are (-6,5).

(ii) Distance of B from the Y-axis = OM = 5 units

Distance of B from the X-axis = BM = 4 units

Hence, the coordinates of B are (5,4).

(iii) Distance of C from the Y-axis = ON = -3 units

Distance of C from the X-axis = CN = 2 units

Hence, the coordinates of C are (-3,2).

(iv) Distance of D from the Y-axis = OP = 2 units

Distance of D from the X-axis = DP = -2 units

Hence, the coordinates of D are (2,-2).

(v) Distance of E from the Y-axis = OL = -1 units

Distance of E from the X-axis = AL = -4 units

Hence, the coordinates of E are (-1,-4).
