Question

use the diagram below to answer the following: 1. name the intersection of plane adc and plane bfe. 2. name the intersection of plane dcg and plane bfg. 3. name a point that is collinear with e and h.

Explanation:

Step1: Recall plane - intersection property

Two non - parallel planes intersect in a line. For plane ADC and plane BFE, the common line is $\overleftrightarrow{AB}$.

Step2: Analyze second pair of planes

For plane DCG and plane BFG, the common line is $\overleftrightarrow{CG}$.

Step3: Identify collinear point

Points on the same straight line are collinear. Point J is on the line segment EH, so it is collinear with E and H.

Answer:

1. $\overleftrightarrow{AB}$
2. $\overleftrightarrow{CG}$
3. J
