Supplement angles = 180° So 180° - 120° = 60° Complementary angles = 90°

A quadrilateral is a four sided shape. The regular quadrilateral shape is a square or rectangle: each angle is 90 degrees. An irregular shape is when the angles are different than the angles they should be.E.g: Square = 90. 90. 90. 90. -360 Degrees.Triangle= 60. 60. 60. 60. -180 Degrees.The irregular shapes would have different angles.Hope you understand :)
There is no such regular polygon with 45 degree interior angles; the smallest interior angles in regular polygons are 60 degrees, which is found in a triangle.
It is an equilateral triangle which in fact has three 60 degree angles

Rhombus
Both 60 degree angles are congruent
Differences: Squares have 4 sides / equilateral triangles have 3 sides. Squares have 90 degree angles / equilateral triangles have 60 degree angles. Squares have 2 diagonals / equilateral triangles have none Similarities: All sides of the shape are congruent All angles of the shape are congruent
An equilateral triangle has 3 interior 60 degree angles but a right angle triangle can have 3 interior angles of 90, 60 and 30 degrees
A trapezoid, if the angles going around the shape are 90, 90, 120, 60.
