Final answer:
When two planes intersect at a right angle, it means they meet each other at a 90-degree angle. Line AB and line CG lie in plane X but do not intersect, while line RS lies in plane Y. The vectors A, Ax, and Ay form a right triangle.
Step-by-step explanation:
In physics, when two planes intersect at a right angle, it means that they meet each other at a 90-degree angle. Line AB and line CG lie in plane X but do not intersect, meaning they are parallel to each other and lie in the same plane. Line RS lies in plane Y.
This situation can be visualized using a right triangle. If we consider the vectors A, Ax, and Ay, they form a right triangle. Ax and Ay are defined as the components of A along the x-axis and y-axis respectively. A right triangle has one angle of 90 degrees, which can be seen where the two lines AB and CG intersect.
