Mell How many sides is 1080?
8 sides
The polygon with an interior angle sum of 1080° is an octagon, or a polygon with 8 sides.
What polygon has an interior angle sum of 1080?
octagon
The sum of the measures of the interior angles of an octagon is 1080° .
How many sides does a polygon have if the sum of its interior angles is 1080 O?
Question 362249: How many sides does a polygon have if its angle sum is 1080 degrees? The interior angles of a polygon add up to 180(n-2). The answer is 8 sides.
How many sides does a polygon have if the sum of its interior angles is 1080 degrees and each interior angle measures 135 degrees?
Question 859614: the sum of the interior angles of a convex polygon is 1080 (a)how many sides does the polygon have, (b)suppose the polygon is reular, what is the measure of each interior angles? There are 8 sides. Each interior angle is 135 degrees. This is if the polygon is regular.
What do you call a shape with 20 sides?
Icosagon
A 20 sided shape (polygon) is called Icosagon. This is called 1 quadrillion. Polygons are usually named according to the number of sides, combining a Greek-derived numerical prefix with the suffix -gon, e.g. What is the interior angle of a 20 sided polygon?
How many sides does a regular decagon have?
10
Decagon/Number of edges
In geometry, a decagon (from the Greek δέκα déka and γωνία gonía, “ten angles”) is a ten-sided polygon or 10-gon. The total sum of the interior angles of a simple decagon is 1440°. A self-intersecting regular decagon is known as a decagram.
What is the formula for interior angles?
The formula for calculating the sum of interior angles is ( n − 2 ) × 180 ∘ where is the number of sides. All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides.
What is a 6 sided shape called?
hexagon
A six-sided shape is a hexagon, a seven-sided shape a heptagon, while an octagon has eight sides… There are names for many different types of polygons, and usually the number of sides is more important than the name of the shape. In case of two dimensional shapes, a shape with 100 sides is called Hectogon.
What is the interior angle of 1080 degrees?
The interior angles of an octagon add up to 1080 degrees If the sum of the interior angles of a polygon equals 1080 degree’s what is the measure of each interior angle of the polygon? Sum of interior angles = (n-2)*180 degrees = 1080 deg So (n-2) = 1080/180 = 6 => n = 8. The polygon is, therefore, an octagon.
How many sides does the polygon FHG have?
Because the octagon is regular, all of its sides and angles are congruent. Thus, the measure of each angle is equal to the sum of its angles divided by 8. Therefore, each angle in the polygon has a measure of 1080/8 = 135 degrees. This means that angle FHG has a measure of 135 degrees.
What is the exterior angle of an 8 sided polygon?
The exterior angles of a regular n-sided polygon are equal to 360/n degrees. In this case n = 8 so Exterior angles are 45 degrees, making the interior angles 145 degrees; b: Total of interior angles of n-sided polygon is (2n -4) right angles, or 180n – 360 degrees.
How many sides has a regular polygon whose sum of Interior?
1. if the measure of an interior angle of a regular pentagonis 108 degrees, then the angle sum of that regular pentagon must be: A. 120 degrees B. 360 degrees C. 540 degrees D. The sum of the interior angles of a regular polygon equals 1260 degrees.
