The circle Flashcards
1
Q
A set of all points equidistant from the fix point.
A
Circle
2
Q
What is the standard form of the circle’s also called?
A
center-radius form
3
Q
center radius form formula
A
(x-h)^2+(y-k)^2=r^2
4
Q
center radius form formula
A
(x-h)^2+(y-k)^2=r^2
5
Q
What is the (h,k) of the center radius form?
A
midpoint
6
Q
Location of the point if the (x-h)^2+(y-k)^2 is <, =, or > than the r^2
A
if the (x-h)^2+(y-k)^2 is less than the r^2 then it’s inside the circle, if equal then it’s on the circumference of the circle, and if it’s greater then it’s outside the circle.
