Revelian Spatial Reasoning Questions and Answers Flashcards

A clock shows exactly 3:00. What is the angle between the hour and minute hands?

Answer: 90°

At 3:00, the minute hand points to 12 and the hour hand points to 3, which are exactly one-quarter of the clock face apart, forming a 90° angle.

A rectangle has its length doubled and its width halved. What happens to the area?

Answer: It stays the same

Area = length × width; doubling one dimension and halving the other cancels out, leaving the area unchanged.

A shape is reflected across a vertical axis. If the original shape points to the right, which direction does the reflected shape point?

Answer: Left

Reflection across a vertical axis swaps left and right, so a shape pointing right becomes one pointing left.

How many lines of symmetry does a regular hexagon have?

Answer: 6

A regular hexagon has 6 lines of symmetry: 3 passing through opposite vertices and 3 through midpoints of opposite sides.

If you look at a transparent clock face from the back, where does the number that is normally at 9 appear?

Answer: At 3

Viewing a clock from behind mirrors it horizontally, so the 9 and 3 swap positions.

Which 3D shape has the most edges among the following options?

Answer: Cube (6 faces)

A cube has 12 edges, compared to 6 for a triangular pyramid, 8 for a square pyramid, and 9 for a triangular prism.
