I'm assuming you mean a shape with 8 sides or angles. If so, you are speaking about an octogon.
To work out the angle of any 'perfect shape' you use this formula: interior angle =((number of sides - 2) x 180)/ number of sides for an octagon: interior angle =((8-2) x 180 )/ 8 = 135 degrees

I'm assuming you mean a shape with 8 sides or angles. If so, you are speaking about an octogon.
It is a regular octagon which has 8 sides
It is an Octagon.
An octangle.

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.
Interior angle = 3 x exterior angle. Hence Int Ang + Ext Ang = 180 Substituting 3 x Ext + Ext = 180 4 Ext = 180 Ext Angle = 180 / 4 = 45 degrees. And Exterior Ang;e = 360 / number of sides. number of sides = 360/ exterior angle No. of sides = 360/45 = 8 Hence the number of sides of the polygon is '8' . It is named as an OCTAGON.

45
If one interior angle measures 172° then the corresponding exterior angle measures 180 - 172 = 8°. The number of sides = 360 ÷ 8 = 45.
To work out the angle of any 'perfect shape' you use this formula: interior angle =((number of sides - 2) x 180)/ number of sides for an octagon: interior angle =((8-2) x 180 )/ 8 = 135 degrees
