In the straightedge and compass construction of the perpendicular line below, how do you know that EF 1 GH?
A. The angles at the intersection of the two lines can be proven to be
congruent and supplementary, so they meet at a right angle and
the lines are perpendicular.
B. The angles at the intersection of the two lines can be proven to be
congruent and complementary, so they meet at a right angle and
the lines are perpendicular.
C. The angles at the intersection of the two lines can be proven to be
congruent, so they meet at a right angle and the lines are
perpendicular
D. The angles at the intersection of the two lines can be proven to be
sunnlementary so they meet at a richt angle and the lines are
perpendicular
