10 cards from this deck
Set of all points equal distance from a centre
Distance from centre to any point on circumference
Line through centre connecting two points; max distance
x2+y2=r2x^2 + y^2 = r^2x2+y2=r2
Pythagorean theorem
If (x,y)(x, y)(x,y) on circle, then (−x,−y)(-x, -y)(−x,−y) also on circle
Substitute coordinates into equation x2+y2=r2x^2 + y^2 = r^2x2+y2=r2
Diameter = 2×2 \times2× radius
Infinitely many (any line through centre)
x-axis, y-axis, y=xy = xy=x, and y=−xy = -xy=−x
