WebOct 22, 2024 · For a regular heptagon, each exterior angle has an equal measure x º, so that 7 x º = 360º, or x º ≈ 51.43º. Interior angles supplement exterior angles, so they each have measure 180º - x º ≈ 128.57º. Multiply this by 7 to get a total of 900º. Advertisement WebDec 11, 2024 · This works out perfectly: The measure of each internal angle of an equilateral triangle is 60 degrees, and 6 × 60 = 360, which is exactly what we need around a single point. Similarly for squares: Four squares around a single point at 90 degrees each gives us 4 × 90 = 360. But starting with pentagons, we run into problems.

Sum of the measures of the interior angles of a heptagon = (n - 2) × 180 º = (7 - 2) × 180 º = 5 × 180 º = 900 º Therefore, the sum of the measures of the interior angles of a heptagon is 900 º. security gates for babies
