Question

Frank has a compass but no straightedge. Which of the following can Frank construct with just the compass?

A.
a triangle

B.
a square

C.
a hexagon

D.
a circle

Answer 1

D A circle because a compass only draw circles or half circles

Answer 2

(D) A circle

Explanation:

The question says that Frank does not have a straightedge. All the options except for a circle have straight lines in them, which means that you need a straightedge to draw them. However, a circle does not require a straightedge since it has no straight lines. This shows that the only possible answer would be D (a circle).
