Question

now, to make sure all of your videos attract an increase in viewership, you want to redesign your channel’s backdrop and thumbnails to make them more visually appealing. you’re considering a number of different shapes such as circles, triangles, squares, and other parallelograms. which of these shapes doesn’t have any parallel sides?

Explanation:

A circle has no straight sides at all, so it cannot have parallel sides. Squares and other parallelograms are defined by having two pairs of parallel sides. While some triangles (like equilateral, isosceles, scalene) have no parallel sides, the key is that among the listed shapes, the triangle is the one with no parallel sides (circles are curved, not straight-sided, but the question focuses on shapes with sides, and triangles are the polygon here with no parallel sides).

Answer:

Triangle
