Below are sample questions representative of the exercises included on this worksheet and related 6.94 Find Lines of Symmetry in Regular Polygons skill assessments:

Problem 1Difficulty: Mastery

A regular sign is shaped like a regular 20-gon with labels Y1 through Y20. Which proposed line is a symmetry line of the sign?

Adashed line through the midpoint of side Y19Y20 and the midpoint of side Y8Y9

Bdashed line through Y19 and Y8

Cdashed line through the midpoint of side Y19Y20 and the midpoint of side Y9Y10

Ddashed line through the midpoint of side Y20Y1 and the midpoint of side Y11Y12

Solution & Explanation:In a regular 20-gon, a line through the midpoints of opposite sides is a line of symmetry. Side Y19Y20 is opposite side Y9Y10, so their midpoint line is correct.

Problem 2Difficulty: Mastery

The labeled diagram shows a regular 16-gon with vertices X1 through X16. Which dashed line should be selected as a true symmetry line?

Adashed line through X14 and X5

Bdashed line through X14 and X6

Cdashed line through X15 and X8

Ddashed line through the midpoint of side X14X15 and the midpoint of side X5X6

Solution & Explanation:In a regular 16-gon, a line through opposite vertices is a line of symmetry. X14 and X6 are opposite vertices, so the line through them folds the polygon into matching halves.

Problem 3Difficulty: Mastery

A craft stencil is a regular 17-gon labeled W1 through W17. Which answer choice marks a correct line of symmetry?

Adashed line through W3 and the midpoint of side W11W12

Bdashed line through W3 and W11

Cdashed line through W3 and the midpoint of side W12W13

Ddashed line through the midpoint of side W3W4 and the midpoint of side W11W12

Solution & Explanation:A regular 17-gon has symmetry lines that pass through one vertex and the midpoint of the opposite side. From W3, the opposite side is W11W12, so that line makes two matching halves.
