Answer:
1.bd=~ed given
2.CD=~fd given
3.<bdc=<edf
4.triangle BCD=~triangle def by s.s.a.axiom
5.BC=~ef the corresponding side of congruent triangle are equal
Explanation:
in triangle qrs &rst
- rs=~rs common side
- qr=~st midpoint bisect that side
- <qsr=<rst midpoint bisect that angle
4.traingle qrs =~rst by s.s.a.axiom
5.<rqs=<rts since the corresponding angle of congruent triangle are equal
temperature and amount of rainfall
