Question

In the right triangular prism above, line TI and line NG are _____.

A. skew lines
B. intersecting lines, but not perpendicular
C. perpendicular lines
D. oblique lines
E. parallel lines

Answer 1

In a right triangular prism, line TI and line NG are perpendicular lines (option C).

Step-by-step explanation:

To understand this, let's first consider what perpendicular lines are. Perpendicular lines are lines that intersect at a 90° angle. In a right triangular prism, line TI and line NG intersect at a right angle, which means they are perpendicular to each other.

This can be visualized by imagining a right triangle inside the prism, where the triangle's hypotenuse (line TI) is perpendicular to the base (line NG).

Therefore, the correct answer is option C: perpendicular lines.
