Solution

user avatar imageAnswer The number of pairs of parallel sides are as follows: - Regular heptagon: 0 - Regular octagon: 4 - Regular hexagon: 3.ExplanationStep 1: Analyze the definition of parallel sides within polygons. - A regular heptagon has 7 sides of equal length, but no sides are parallel because each exterior angle is not 180 degrees, meaning the sides will never be parallel to each other. - A regular octagon has 8 sides of equal length. Considering its geometry, there will be pairs of opposite sides that are parallel to each other. - A regular hexagon has 6 sides of equal length. Similar to the octagon, there will be pairs of opposite sides that are parallel. Step 2: Determine the number of pairs of parallel sides for each shape. - For the regular heptagon, since no sides are parallel, it has 0 pairs of parallel sides. - For the regular octagon, we need to calculate how many pairs of opposite sides are parallel. - For the regular hexagon, we also need to calculate how many pairs of opposite sides are parallel. Let's calculate for the octagon and hexagon.Step 3: Present the final answers for each shape. - For a regular heptagon, the number of pairs of parallel sides is 0. - For a regular octagon, the number of pairs of parallel sides is 4. - For a regular hexagon, the number of pairs of parallel sides is 3.Click to rate:38.5(39 votes)Search questionBy textBy image/screenshotDrop your file here orClick Hereto upload
