Question

1. which phrase best describes this polygon? convex dodecagon concave hexagon concave dodecagon convex hexagon

Explanation:

1. First, identify the number of sides: A star - shaped polygon like this (a regular star polygon) with 12 sides is a dodecagon (a dodecagon has 12 sides, a hexagon has 6 sides).
2. Then, determine if it is concave or convex: A concave polygon has at least one interior angle greater than 180 degrees or has "indentations". This star - shaped polygon has indentations, so it is concave.
3. Eliminate the wrong options:

• "convex dodecagon" is wrong because it is not convex.
• "concave hexagon" and "convex hexagon" are wrong because it has 12 sides, not 6.

Answer:

C. concave dodecagon (assuming the options are labeled A, B, C, D with C being "concave dodecagon")
