Prove angle bisector theoram |
| Answer» This\xa0theorem\xa0states that an\xa0angle bisector\xa0divides the opposite side of a triangle into two segments that are proportional to the triangle\'s other two sides. In the triangle below, that\'s AB/BD = AC/CD. We then used the\xa0theorem\xa0to find the missing length in a triangle with an\xa0angle bisector.\xa0An\xa0angle bisector\xa0is a line or ray that divides an\xa0angle\xa0into two congruent\xa0angles\xa0. ... Some textbooks call this\xa0Angle Bisector\xa0Theorem , but this name is usually used for another theorem about\xa0angle bisectors\xa0in a triangle.\xa0Example\xa0: In the figure, →BD is an\xa0angle bisector. | |
