How many obtuse angles in a parallelogram
A parallelogram has rotational symmetry of order 2 (through 180°) (or order 4 if a square). If it also has exactly two lines of reflectional symmetry then it must be a rhombus or an oblong (a non-square rectangle). If it has four lines of reflectional symmetry, it is a square.

Did you know?
WebIt's just one of the 3 main angles in math. Acute angles are angles that are less than 90 degrees. Right angles are angles that are exactly 90 degrees. Obtuse angles are angles that are more than 90 degrees. You'll work with these three types of angles a lot more as you advance in math. 6 comments ( 16 votes) Show more... gavin 6 months ago WebThe Square. the little squares in each corner mean "right angle". A square has equal sides (marked "s") and every angle is a right angle (90°) Also opposite sides are parallel. A square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length).
