1. DEFINITION OF CIRCLE
Collection of points that have an equal distance from certain point
2. ELEMENTS OF CIRCLE
3. MATERIAL PREVIOUSLY Distance between two points
Distance between an arbitrary point and an
arbitrary line.
4. EQUATION OF CIRCLE Center at (0,0)
Center at (a,b)
6. TRY IT
Determine the posisition of points (4,-5),
(3,7), (8,9) and (2,1) with respect to a circle
having an equation of X2 + Y2 = 58.
HOME WORK Given the equation of a circle
X2 + Y2 – 4x – 6y – 12=0 a.) Determine the power value of
points A(1,2), B(6,6), and C(8,2).b.) Then determine the position of
points A, B, and C with respect to the circle.
