What shape have 4 sides and 4 vertices?

Properties of a Quadrilateral: A quadrilateral has 4 sides, 4 angles and 4 vertices. A quadrilateral can be regular or irregular. The sum of all the interior angles of a quadrilateral is 360°.

What is the formula for an octagon?

The Math. A regular octagon is an eight sided polygon where all of the sides are the same length (s), with a height (h), one can create a octagon shaped object (e.g. column or planter) such as an octagon column is derived by the following formula: Where the Area =`2(1 + sqrt(2))*s^2` for an octagon.

What shapes have vertices?

Vertices are the points, or corners, in geometrical and mathematical shapes where two or more lines meet but do not cross, according to Math Open Reference. Vertices can exist in two-dimensional and three-dimensional shapes. The singular form of vertices is vertex.

How do you calculate the angle of an octagon?

Subtract two from the number of sides in an octagon. Since an octagon has eight sides, subtract two from eight to get six. Multiply six by 180 to find the total number of degrees in an octagon equals 1,080. Add the angle measures of the seven known angles to find the sum of those angles.
