In this activity students will explore the following theorems and corollaries:The measure of an inscribed angle is equal to half the measure of its intercepted arc.If two inscribed angles intercept the same arc, then the angles are congruent.If a quadrilateral is inscribed in a circle, then its opposite angles are supplementary.The measure of an angle formed by a chord and a tangent is equal to half the measure of the intercepted arc.Students should use Geogebra, Desmos, Geometer's Sketchpad, or
