12.05 Angles from intersecting chords, secants, and tangents

Interactive practice questions

Find the value of $x$x.

A circle is divided into four unequal sections by two intersecting chords. The location of the intersection point is not specified. The intersecting chords divide the circle's circumference into four unequal arcs. Two arcs are highlighted. The left arc, colored green, is $154^\circ$154°. The right arc, colored orange, is $52^\circ$52°. The other two arcs opposite each other are colored black and are not labeled. An angle at the intersection measures $\left(x\right)$(x) and intercepts the green arc. The vertical angle to the angle measuring $\left(x\right)$(x) and intercepts the orange arc, is not labeled.

II.G.C.2

Identify and describe relationships among inscribed angles, radii, and chords. Include the relationship between central, inscribed, and circumscribed angles; inscribed angles on a diameter are right angles; the radius of a circle is perpendicular to the tangent where the radius intersects the circle.
