Find the measure of each interior angle of a regular octagon. (A regular polygon is one that has all the same sides and angles).

NemiM [27]

The interior angle of a regular octagon is 135 degrees.

<h3>What is an octagon?</h3>

An octagon is a polygon that has 8 sides. Therefore, a regular octagon is a octagon with all it sides and angles equal to each other.

Therefore, the sum of angles in an octagon is each interior angle multiply by the number of sides.

Therefore,

n = number of sides = 8

Hence,

interior angle = (n - 2)180 / n

interior angle = (8 - 2)180 / 8

interior angle = 6 × 180 / 8

interior angle = 1080 / 8 = 135°

The diagonals of quadrilateral EFGH intersect at D(?3,4). EFGH has vertices at E(3,7) and F(?4,5). What must be the coordinates

Katen [24]

Answer:

G(3, 1), H(2, 3)

Step-by-step explanation:

When D is the midpoint of EG, it means ...

D = (E + G)/2

G = 2D -E = 2(3,4) -(3,7) = (2·3-3, 2·4-7) = (3, 1)

Likewise, H is ...

H = 2D -F = 2(3,4) -(4,5) = (2·3-4, 2·4-5) = (2, 3)
