Question

If you arrange an odd number of triangles in the following pattern, how many sides will the resulting polygon have?

• A. 4
• B. 5
• C. 3
• D. cannot be determined

Answer 1

Answer: (A), (C)

The correct options are
A 4
C 3

If there is only 1 triangle present, the figure will be:
If there are 3 triangles, then the figure will look like:
If there are 5 triangles in the pattern, then the figure will look like:
So, if we arrange 1 triangle, the resulting polygon is a triangle. If we arrange 3 or more triangles in the given pattern, we get a quadrilateral.
So, the correct answers are 3 and 4.
