WebWe can learn a lot about regular polygons by breaking them into triangles like this: Notice that: the "base" of the triangle is one side of the polygon. the "height" of the triangle is the "Apothem" of the polygon. Now, the area of a triangle is half of the base times height, so: … A regular polygon has all angles equal and all sides equal, otherwise it is irregular : …

WebAnswer (1 of 4): The sum of the interior angles of a polygon = 1080. (n-2)x180 = 1080, or n-2 = 6, or n = 8 No. of diagonals in an octagon (n=8) is given by n(n-3)/2 = 8(8–3)/2 = 8*5/2 = 20 So the octagon has 20 diagonals.

WebA number of diagonals is: d = n ( n – 3) 2 = 6 ( 6 – 3) 2 = 9. The sum of the measures of all interior angles is: ( n – 2) ⋅ 180 ∘ = 4 ⋅ 180 ∘ = 720 ∘. The measure of each interior angle: 720 ∘: 6 = 120 ∘. The center of an … WebBy setting them equal to each other, you can find the value of x. To set them equal, what you need to do is place the equations on either side of an equal sign. (8x-184=4x-148) … WebAll interior angles: 3. All exterior angles: 4. All vertices: 5. All sides: 6.
