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

Prove that opposite angles of an inscribed shape are supplementary, (equaling to 180 degrees). in other words, if a quadrilateral was inscribed in a circle, prove how the opposite angles are equal to 180 degrees. note: you cannot say "because of the inscribed angles conjecture."

given: abcd is a parallelogram. prove: ∠a and ∠d are supplementary. by the definition of a parallelogram, ab∥dc. ad is a transversal between these sides, so ∠a and ∠d are ? angles. because ab and dc are ? , the same-side interior angles must be ? by the same-side interior angles theorem. therefore, ∠a and ∠d are supplementary.
