Complete the proof.

m\angle B = m\angle E 

Def. of \perp

\overline{DE}\perp\overline{EF} 

m\angle B = 90^o 

m\angle E = 90^o 

Complete the proof.

100^o 

Def. of \perp

180^0 

90^o 

Complete the proof.

Def. of \perp

m\angle 2 = m\angle 3 

m\angle 1 = m\angle 2 

m\angle 1 = m\angle 3 

\overline{AB}\perp\overline{BD} 

Complete the proof.

\angle 9\cong\angle 11 

\angle 1\cong\angle 11 

Def. of \perp

\angle 1\cong\angle 9 

Complete the proof.
