Interior angle = 135
So exterior angle = 180 - 135 = 45
Sum of exterior angles is 360 so number of exterior angles = 360/45 = 8.

A regular polygon has congruent sides and equal interior angles such as a square or an equilateral triangle
A 12 sided shape with equal sides and with equal interior and exterior angles
No because although it has 4 equal sides its 4 interior angles are acute and obtuse
It means that the sides are of equal lengths and that the interior angles are of equal sizes
A regular shape has 3 or more sides of equal lengths and equal interior angles
It will have 12 sides

Angle and sides. Interior angles being equal means that exterior angles are equal.
A regular polygon has congruent sides and equal interior angles such as a square or an equilateral triangle
A 12 sided shape with equal sides and with equal interior and exterior angles
No because although it has 4 equal sides its 4 interior angles are acute and obtuse
It means that the sides are of equal lengths and that the interior angles are of equal sizes
It would have 10 sides.
The Octagon is a regular shape if all the sides and all of the interior angle s are equal. If the sides and or angles are different the shape is irregular. However, even irregular octagons can have an axis of symmetry.
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 900 degrees
