No. "Congruent" things are equal, identical, same, twin, indistinguishable, able to substitute for each other. Our staff points out that there is some difference between 60 and 120.
120 degrees.
A regular polygon having an interior angle of 120 degrees will have 6 sides and is called an hexagon.
well if its 120 degrees it must have 3 sides
Exterior angle = 360/120 = 3 degrees. So interior angle = 180-3 = 177 degrees.
If its a regular polygon and each inside angle is 120 degrees then it is a 6 sided hexagon
Interior angle = 120 degrees Exterior angle = 60 degrees
Rhombus.
No. For example 30 and 60 degrees are complementary angles. Their supplementary partners are 150 and 120 degrees.
360/120=number of sides. There are 3 sides.
No. The angles must be an included angle, between the sides to guarantee congruence. For an example. imagine a triangle with two equal sides and a 60 degree angle between them and another triangle with the same two equal sides and a 120 degree angle between them.
