Definitions

• Locus Points - points that satisfy a given condition
• Compound Locus - points that satisfy 2 given conditions
• Inscribed Angle - an angle in a circle whose vertex is on the circle and whose sides are chords (( segment whose endpoints are on the circle. ))
• Intercepted Arc - an arc on the interior of an inscribed angle.

Equation of a Circle

• ( x - h )² + ( y - k )² = r²
• EX : A circle has the radius measuring 3 inches and passes through the point ( 3 , -4 ).
• answer : ( x - 3 )² + ( y + 4 )² = 9.
