How many angles in a octagon?

There are no angles they are all obtuse angles


Are all sides of an octagon the same size?

Not necessarily. If all sides are the same size, and all angles are also the same, then it is called a "regular octagon". But an irregular octagon is still an octagon - the only requirement is that it have 8 sides.


What do the all the angles on a straight line add up to?

All The Angles On A Straight Line Add Up To 180 Degrees.


If a shape is a regular octagon with eight sides what must be true?

All 8 sides must be equal in length Interior angles add up to 1080 degrees Exterior angles add up to 360 degrees Each interior angle measures 135 degrees Each exterior measures 45 degrees It has 6 triangles It has 20 diagonals


Does an octagon always have perpendicular sides?

No! An Octagon that is not regular can have 8 lines that meet at any angle provided that they ultimately create an 8 sided enclosed shape.A regular Octagon, however, will always have pairs of sides that are perpendicular. In a regular Octagon the interior angles must all be equal and must sum to 1080 degrees (6 x 180 degrees). Accordingly the interior angles will all equal 135 degrees. As a consequence the exterior angles equal 45 degrees and since two exterior angles equal 90 degrees every side will be perpendicular to the sides that are adjacent but one in either direction. Likewise opposite sides (4 exterior angles apart) will be parallel.ThanksNoob headIf it is regular, yes. Each side of a regular octagon has two other sides that are perpendicular to it.

Degrees of an octagon?

All angles of an octagon must add up to 1080 degrees. A "regular" octagon has all equal angles, which are all 135 degrees. Other angles are possible though. As long as the shape has 8 sides and all angles add up to 1080, it is still classified as an octagon.


How many angles are in an octagon?

eight There are eight angles in an octagon, all being 135 degrees, and they all add up to 1080 degrees.


What do all the angles in a octagon add up too?

All of the angles in an octagon add up to 810 degreesIf you want to know what one of the angles equals you do 810 divided by 6 to get 135Another contributor's answer:An octagon is an eight sided polygon.Interior angles total 1080 degrees.Exterior angles total 360 degrees.


What are the differences between a triangle and an octagon?

Triangle has 3 sides, 3 vertices (corners) whose interior angles add up to 180. Octagon has 8 sides, 8 vertices, whose interior angles add up to 1080 degrees. A regular triangle (all sides equal, all angles equal), has interior angles of 60 degrees. A regular octagon (all sides equal all angles equal), has interior angles of 135.


How many angles does an octagon have?

An octagon has 8 angles. An octagon has the same number of angles as it does sides. Eight. All of the angles measure 135 degrees, and all the angles together are 1080 degrees.


Can an octagon have equal angles?

Yes. A regular octagon must have equal angles, but an irregular octagon cannot have all its angles equal


What is the total of all the measures of all the angles in a regular octagon?

Interior angles add up to 1080 degrees Exterior angles add up to 360 degrees So: 1080+360 = 1440 degrees


How muck angles does an octagon have?

An octagon has 8 angles, because it has 8 sides. The sum of all of the angles add up to 1080 degrees. You can find the sum of all the angles in any polygon by using this formula: (n-2) x 180 degrees, with n being the number of sides.
