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