A. Given ADI bisector BC
1. Why is AB = BCP
2. Why 112ADB and m_ADC right angles?
3. Why is A ABC isosceles?
4. I AB = +0cm, how long is AC?
5. 11 EC - 25.5 cmn, then BE-
6. Ir the in ABC
60°, then m ACB
7. 11 BD = 2x and CD = 12, what is x?
8. If the m ABC is 60°, what is the mZBADP
9. If the m ABC is 60°, what is the m EBD?
10. If the measure of BC = 29 cm, what is the
mcasure DC?​
