NCSSM placement test 2024 with answers

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 arc. Angle formed by 2 chords intersecting in a circle is equal to the sum of the arcs divided by 2. Angle formed by 2 secants is equal to the major arc minus the minor arc divided by 2. Angle formed by a secant and a tangent is equal to the major arc minus the minor arc divided by 2. Angle formed by two tangents is equal to the major arc minus the minor arc divided by 2. Lengths of 2 intersecting chords part of the first chord times the other part of the first chord equals a part of the second chord times the other part of the second chord. Lengths of an intersecting diameter and chord that meet at right angles (perpendicular) if a diameter meets a chord at a right angle (perpendicular), the diameter divides the chord into 2 equal parts. Lengths of 2 intersecting secants the whole length of the first secant times the outside length of the first secant equals the whole length of the second secant times the outside length of the second secant.
