Lesson 7.4

Conjectures Geo Sketchpad

C-68 The measure of an inscribed angle in a circle is half the measure of the arc it intercepts.

C-69 Inscribed angles that intercept the same arc are congruent.

C- 70 Angles incribed in a semicircle are right angles.

C-71 The opposite angles of a quadrilateral inscribed in a circle are supplementary.

A + C = 180 B + D = 180

Cyclic quadrilateral - A quadrilateral incribed in a circle.

C-72 Parallel lines intercept congruent arcs on a circle.
