Question

1. this diagram is a straightedge and compass construction of a line perpendicular to line ab passing through point c. which segment has the same length as segment ea? a. ec b. ed c. be d. bd

Explanation:

Step1: Identify construction arcs

In perpendicular construction, arcs from A and D (on AB, equidistant from C) intersect at E.

Step2: Radii of equal arcs

EA and ED are radii of the same arcs from A and D, so EA=ED.

Answer:

B. ED
