An octangle.
An angle cannot have 8 sides. If you're thinking of a shape with 8 sides, that's an octagon.
It is an angle that on both sides it has a right angle
It is an Octagon.
8
If the exterior angle is 45 degrees then it will have 8 sides
Providing that it is a regular polygon it will have 8 sides.
Right Angle! (:
An inscribed angle.
I'm assuming you mean a shape with 8 sides or angles. If so, you are speaking about an octogon.
45
If one interior angle measures 172° then the corresponding exterior angle measures 180 - 172 = 8°. The number of sides = 360 ÷ 8 = 45.
No kind of octagon has six sides. An octagon has 8 sides. A hexagon has 6 sides.
