Question

question select all the figures that are octagons.

Explanation:

Step1: Recall octagon definition

An octagon is a polygon with 8 sides and 8 angles.

Step2: Analyze each figure

• Top - left (blue): Not closed, so not a polygon, let alone an octagon.
• Top - right (green): Closed, 8 sides → octagon.
• Middle - left (purple): 8 sides → octagon.
• Middle - right (red): 8 sides (2 long, 6 short) → octagon.
• Bottom - left (light - colored): 6 sides → hexagon, not octagon.
• Bottom - right (purple - shaped with gap): Not closed (has a gap), so not a polygon, let alone an octagon.

Answer:

The green octagon (top - right), the purple octagon (middle - left), and the red octagon (middle - right)
