So really there are 5 named categories. But in a polygon, there would never exist a straight angle, because then the two 'sides' would just become 1 side.
yes and all have right angles
If the figure has only four sides all together, then it's not possible for all four angles to be acute.
In all parallelograms, opposite angles and opposite sides are congruent. If all four sides are congruent, it's a rhombus. If all four angles are congruent, it's a rectangle. If all four sides and all four angles are congruent, it's a square.
A square has four right angles and all sides are equal.
A square is a plane rectangle with four equal sides and four right angles, a four-sided regular polygon, and a rhombus having four right angles.
You don't tell us enough information. In a square, there are four sides and four angles. The sides are all equal and the angles are all right angles. In a rectangle, there are four sides and four angles The opposite sides are equal and the angles are all right angles. There is no other shape in which all angles are right angles.
Rectangles have four sides and four angles.
A shape that has four straight sides and four angles is defined as a quadrilateral. If all four angles are right angles, it is a rectangle, and if all four sides are congruent, it is a square.

Obtuse, acute, straight, and right angle.
YesIt does in fact it has all four right angles.
In a quadrilateral the sum of all four angles equals 360º.
All octagons have 8 sides and 8 angles
