User: Select interior, exterior, or on the circle (x - 5) 2 + (y + 3) 2 = 25 for the following point. (5, -3)

User: A polygon has vertices whose coordinates are A(1, 4), B(4, -1), C(-1, -4), and D(-4, 1). The diagonals of this polygon bisect each other. True False

Weegy: A polygon has vertices whose coordinates are A(1, 4), B(4, -1), C(-1, -4), and D(-4, 1). The diagonals of this polygon bisect each other. [ True. The midpoint of A(1, 4), C(-1, -4) is (0 , 0); the midpoint of B(4, -1), and D(-4, 1) is also (0, 0), therefore the diagonals beset each other. ]

On putting the points (5,-3)in equation of circle, if the value is negative then the point lies inside.
Clearly we see (5-5)^2 + (3+3)^2 -25=0
0+0-25=-25 (negative value) hence lies inside.
Actually the point is at center of this circle.

The point of (5, -3) is interior of (x - 5)^2 + (y + 3)^2 = 25 .
(5 , -3) is the center of the circle , so it is interior of the circle .
