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?
