Justify the given statement using the picture above.
1. m21+ m2 = mZABC
2. If B is the midpoint of AD, then AB = BD.
3. If BC bisects FBE, then 2243.
4. If 21 and FBD are supplementary, then m≤1 + m<FBD = 180°
5. If m CBD = 90°, then 2CBD is a right angle.
6. AB+BDAD
7. If m42 = m23, then BC bisects <FBE.
8. If m23+m24 = 90°, then 23 and 24 are complementary.
9. If ZABC and CBD are right angles, then ZABC ≈ ¿CBD.
10. If 21 22 and 22 43, then 21 = 23.
