Tangent - Study guides, Class notes & Summaries

Tangent intersects a circle in only 1 place. Secant intersects a circle in 2 places. Intersection of a tangent and a radius form right angles when they intersect. Equation of a circle x minus h squared plus y minus k squared equals radius squared. Circumference of a circle 2 times pi times radius or pi times diameter. Area of a circle pi times radius squared. Central angle is equal to its intercepted arc. Inscribed angle is equal to ½ its intercepted...
