NCSSM PLACEMENT TEST ACTUAL 2025/2026 QUESTIONS AND 100% CORRECT ANSWERS Tangent - Answer -intersects a circle in only 1 place. Secant - Answer -intersects a circle in 2 places. Intersection of a tangent and a radius - Answer -form right angles when they intersect. Equation of a circle - Answer -x minus h squared plus y minus k squared equals radius squared. Circumference of a circle - Answer -2 times pi times radius or pi times diameter. Area of a circle - Answer -pi times radius squared. Central angle - Answer -is equal to its intercepted arc. Inscribed angle - Answer -is equal to ½ its intercepted arc. Angle formed by 2 chords intersecting in a circle - Answer -is equal to the sum of the arcs divided by 2. Angle formed by 2 secants - Answer -is equal to the major arc minus the minor arc divided by 2.Angle formed by a secant and a tangent - Answer -is equal to the major arc minus the minor arc divided by 2. Angle formed by two tangents - Answer -is equal to the major arc minus the minor arc divided by 2. Lengths of 2 intersecting chords - Answer -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) - Answer -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 - Answer -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. Lengths of an instersecting secant and tangent - Answer -the whole length of the first secant times the outside length of the first secant equals the length of the tangent squared. Lengths of intersecting tangents - Answer -Tangents to a circle sharing a common vertex are equal. Angles - Answer -acute angles are less than 90 degrees. Right angles are 90 degrees. obtuse angles are between 90 and 180 degrees. Straight angles are 180 degrees and reflex angles are greater than 180 degrees. Adjacent angles - Answer -share a common vertex, a common side, but not common interior points.Complementary angles - Answer -2 angles when added together that equal 90 degrees. They do not have to be adjacent angles. Supplementary angles - Answer -2 angles when added together that equal 180 degrees.They do not have to be adjacent angles. Vertical angles - Answer -vertical angles are congruent. Alternate interior angles - Answer -alternate interior angles are congruent. Corresponding angles - Answer -corresponding angles are congruent. Sum of the angles in a triangle - Answer -the
