Math Worksheets

High School Math based on the topics required for the Regents Exam conducted by NYSED to help students learn how to solve problems involving the angles and arcs formed by tangents, secants, and chords of circles.

Angles in a Circle

This episode deals with angles formed with vertices inside the circle.

Angle formed by 2 chords in a circle

Learn problem solving for angles in circles using properties

A secant is a line, ray, or line segment that intersects a circle in two places.

Three points are covered:

(1) secants that intersect in a circle which divide each other proportionally,

(2) the angle formed by secants which intersects in a circle and is half the sum of the intercepted arcs,

and (3) two secants drawn from the same point outside a circle that form an angle whose measure is half the difference of the intercepted arcs.
