B. Number the sentences in an order to complete an indirect proof. Given: In A EFG, EF - FG Prove: mzE # 900 Therefore the temporary assumption that mLE = 90° must be false. But this contradicts the fact that the sum of the measures of the angles of a triangle is 180. Assume temporarily that mLE = 90" Then meG = 90°, and mLE+ mLF+ m2G = 90 + m2F + 90 > 180 It follows that mzE #e 90°
