Question

1. using the diagram below, describe the relationship as parallel, intersecting, or skew. a) $overline{ab}$ and $overline{bc}$ intersecting b) $overline{ae}$ and $overline{bf}$ parallel c) $overline{ef}$ and $overline{ad}$ skew d) plane $abc$ and plane $abf$ e) plane $aed$ and plane $bfc$ parallel

Explanation:

Step1: Recall plane - plane relationship rules

Two planes are parallel if they do not intersect, and intersecting if they meet at a line.

Step2: Analyze plane ABC and plane ABF

They share the line AB, so they intersect.

Step3: Analyze plane AED and plane BFC

They do not intersect, so they are parallel.

Answer:

d) intersecting
e) parallel
