Answer:
4) The intersection of planes GAB and FEH is the line GH
5) The 3 line segments that intersect at point A are lines AG, AB, and AD
Explanations:
4) Note that the intersection between two planes will give a line:
By properly considering the planes GAB and FEH, you would see that the plane GAB(at the upper side of the box) starts at point G, and the plane FEH ( in the front side of the box) ends at point H. The line that intersects the two planes is the line GH
5) To get the three line segments that intersect at point A, consider all the lines that you can trace from A. You will observe that the lines are AG, AB, and AD
