Question

Consider the diagram.

Planes M and N intersect at line d. Lines a, b, and e are on plane M. Line a is vertical and forms a right angle with line d. Line b is diagonal and goes up and to the right. Line e is at the top of the plane and is close to being horizontal. Line c is on plane N and goes slightly up and to the right.
Lines a and d are

non-coplanar.
parallel.
perpendicular.
skew.

Answer 1

Answer:

perpindicular

Step-by-step explanation:

Answer 2

The line a and line d are perpendicular to each other.

What is a perpendicular line

A perpendicular line is a line that intersect another line at 90 degrees. Perpendicular lines are also called normal lines.

Constructing lines a and d

After constructing the two lines; line a and line intersect or meet each other at 90 degrees to the horizontal.

Thus, we can conclude that the line a and line d are perpendicular to each other.
