Answer asap timed quiz — right answer = brainlist given: quadrilateral abcd inscribed in a circle prove: ∠a and ∠c are supplementary, ∠b and ∠d are supplementary (picture attached) let the measure of = a°. because and form a circle, and a circle measures 360°, the measure of is 360 – a°. because of the theorem, m∠a = degrees and m∠c = degrees. the sum of the measures of angles a and c is degrees, which is equal to , or 180°. therefore, angles a and c are supplementary because their measures add up to 180°. angles b and d are supplementary because the sum of the measures of the angles in a quadrilateral is 360°. m∠a + m∠c + m∠b + m∠d = 360°, and using substitution, 180° + m∠b + m∠d = 360°, so m∠b + m∠d = 180°. what is the missing information in the paragraph proof? inscribed angle polygon interior angle sum quadrilateral angle sum angle bisector mark this and return
