Question

a student thinks that the octagon in the diagram to the right has 16 lines of symmetry explain and correct the students error... select the correct choice below and, if necessary, fill in the answer box to complete your choice. a. the student counted the total number of arrow heads when they should have just counted the number of lines. therefore, the correct answer is b. the student counted the total number of lines when they should have just counted the number of arrow heads. therefore, the correct answer is c. the student did not make an error when determining the lines of symmetry

Explanation:

An octagon (regular) has 8 lines of symmetry. The student likely confused arrow heads with lines of symmetry. Option A says the student counted arrow heads (total 16) instead of lines. A regular octagon has 8 lines of symmetry, so the correct answer is A, with the correct number being 8.

Answer:

A. The student counted the total number of arrow heads when they should have just counted the number of lines. Therefore, the correct answer is 8.
