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.
In a triangle ABC, they are AB, BC and CA.
False - and false ! Not ALL angles are right-angles - and a triangle has THREE sides !
A diagonal joining opposite angles is the principal diagonal. It may or may not bisect the angles, and that does not affect its name.
It has 4 sides and 4 angles There are four interior angles. Each equaling 90 degrees for a total of 360 degrees in all of the angles combined. In fact, quadrangle is another name for rectangle.

There is no specific name for a polygon in which all the angles are different or where the sides are all different.
The answer would be a rhombus, as All rhombuses have 4 angles.
rectangle.
It depends. Most parallelograms don't have all right angles. However, there is a special type of parallelogram that has all right angles. You probably know this shape by its proper name, a rectangle.
It is an irregular polygon
Square and rectangle
Equilateral
Scalene triangle.
Such a rhombus is not possible as it would not have all its sides equal. Or you can keep all angles right angles and call it a square.
how you name a triangle by its angles is like acute, obtuse, or right triangle. you do that by seeing if the angle has a 90 degree angle in it then its a right angle, if all the angles are 90 degrees or less than its an acute triangle. and if the triangle has one angle that is over 90 degrees than it is an obtuse triangle. to name a triangle by its sides is if its equilateral, equiangular, or regular. if its equilateral then all the sides are congruent. if its equiangular then all the angles are congruent. if its regular, then all the sides and angles are congruent to each other (for example and octogon). :)
All four of the angles of a rectangle (and of squares) are right angles.(Its name comes from this : rect-angle.)
