if angle A in quadrilateral Abcd is 80 degrees and there is a diagnol AC then will the diagnol bisect angle A and so is angle BAC 40 degrees? |

Answer» yes ANGLE BAC is 40 degrees Step-by-step EXPLANATION:In quadrilateral ABCD, angle A =80 , diagonal AC Is diagonal of quadrilateral ABCD and angle bisector of Angle Aso, it DIVIDES angle A into angle BAC and angle DACso, m∠BAC=m∠DAC=1/2∠A m∠BAC=1/2∠A m∠BAC=1/2×80 =40 Therefore, m∠BAC=40 Hence PROVED. I HOPE IT IS USEFUL FOR YOU |
