BE by AS. hus EB EB and E C s corresponding arts of congruent triangles. ut since EB and EB are supplementary, they ust each be equal to 90 and therefore E C o we have shown that E C and E C herefore E s the perpendicular bisector of C 1.

Unformatted text preview: The proof is exactly the same as the previous construction except you only have to show that the lines are perpendicular (since you aren’t bisecting any segment). 5. Construct a parallel through a point. Since angle a is congruent to angle b by construction, we have corresponding angles congruent. Thus, the lines are parallel....
