Question

Find the coordinates of a point A,where AB is the diameter of a circle whose centre is (2,-3) and B is (1, 4) *


​

Answer 1

Ans:

Coordinates of A is (3,10)

Step-by-step explanation:

1. Draw XY plane and denote center (suppose O) and point B on plane.

2. B is in first and center is in 4th quadrant, slope of BO is negative so A will be in 4th quadrant.

3. Now use trigonometry between two triangle formed by (A,O,C) and (A,B,D)

4. For point C draw vertical line from B and horizontal line from O, intersection point will be C

5. For point D draw vertical line from B and horizontal line from assumed A
