Solved Example on Parallel Planes
Ques: Identify the parallel planes.
Choices:
A. RST and UZY
B. SXY and RUT
C. WZU and XYT
D. STU and XYT
Correct Answer: C
Solution:
Step 1: Parallel planes are the planes that do not intersect.
Step 2: SXY and RUT are the planes that intersect. Hence, they are not parallel.
Step 3: RST and UZY are the planes that intersect. Hence, they are not parallel.
Step 4: STU and XYT are the planes that intersect. Hence, they are not parallel.
Step 5: WZU and XYT are the planes that do not intersect. Hence, they are parallel.
