prove that the bisectors of the angles formed by two intersecting lines are perpendicular to each other. |
|
Answer» Step-by-step explanation: Suppose TWO angles ABC and CBD are x and y. x+y = 180 deg. The bisector of ANGLE ABC (BE) and the bisector of angle CBD (CF) will FORM angle EBF = (x/2)+(y/2) = 180/2 = 90 deg. Conclusion: If the angle bisectors of two adjacent angles are perpendicular to eaxh other, the adjacent angles are supplementary angle. |
