the base BC of an equilateral triangle lies on the y axis. the co ordinat of C are( 0,-3) .if the origin is the middle of the base BC, what are the co ordinat of A and B
Answers
Answer:
O is the mid-point of the base BC.
Therefore, coordinates of point B are (0,3).
So, BC = 6 units
Let the coordinates of point A be (x,0).
Using distance formula,
AB=
