3 times.
Supplement angles = 180° So 180° - 120° = 60° Complementary angles = 90°

It is a triangle with 90, 60, and 30 degree angles.
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

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.
A triangle with two 60-degree angles is an isosceles triangle. In such a triangle, the third angle must also be 60 degrees to satisfy the triangle sum theorem, which states that the sum of the angles in a triangle equals 180 degrees. Therefore, a triangle with two 60-degree angles is an equilateral triangle, where all three sides are equal in length.
An octagon cannot have 45-degree angles; the internal angles of a regular octagon are each 135 degrees. However, if you want to create an octagonal shape with 45-degree angles, you would need to design an irregular octagon. To form a shape with alternating 45-degree angles, you could use a series of straight lines that connect at 45-degree angles, ensuring that the overall shape closes back on itself to create eight sides.
