An equilateral triangle has 3 equal angles of 60 degrees that add up to 180 degrees
3
3 times.
Supplement angles = 180° So 180° - 120° = 60° Complementary angles = 90°
90 degree angles.90 degree angles.90 degree angles.90 degree angles.
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
3
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.
