Acute, right angle, obtuse and reflex angles.
No. There are lots of different types of parallelograms, which have varied angles.
acute on all of them
All triangles need at least two acute angles
A parallelogram has 2 equal opposite acute angles and 2 equal opposite obtuse angles whereas all 4 angles add up to 360 degrees.
Equilateral - all sides and angles same; isosceles - two sides and angles same; scalene - no sides or angles same; and right-angled - one right angle.

There are right angles, acute angles, obtuse angles, and straight angles.
Equilateral - all sides and angles same; isosceles - two sides and angles same; scalene - no sides or angles same; and right-angled - one right angle.
A square has four right angles.
right angles
No, it is not true that in a polygon all sides and angles are congruent. A polygon with all sides congruent is called a regular polygon, but there are also irregular polygons where the sides and angles can vary. For example, a rectangle has congruent opposite sides but not all sides are equal, and its angles are congruent but not all angles need to be equal in other types of polygons. Thus, congruence in sides and angles only applies to regular polygons.
Regular square: A square with all equal sides and right angles. Rectangle: A square with all right angles but unequal sides. Rhombus: A square with all sides equal in length but angles are not necessarily 90 degrees.
the 4 types of angles are acute obtuse and right! i dont know the 4th 1
They can be acute, right or obtuse but not reflex angles.
