Oh honey, congruent angles have the same measure, and 60 degrees is definitely not the same as 120 degrees. It's like comparing a kitten to a tiger - they're both cats, but one's a whole lot bigger. So, in math terms, those angles are as congruent as a teacup poodle is to a Great Dane.

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.
Angle A + Angle B + Angle C = 180 degrees. 30+90+C=180 120+C=180 C=60 degrees.
60 degrees and 120 degrees
If the interior angle is 120° then the external angle is 180 - 120 = 60° Number of sides = 360 ÷ 60 = 6. The polygon is a Hexagon.
The angle is 120°. Its supplement is 60°.
It can be either acute or obtuse. An acute angle is less than 90 degrees and all 3 angles add to 180 degrees. For example, If two angles are 60 degrees (acute) then the 3rd is 60 degrees (acute). If two angles are 30 degrees (acute) the 3rd is 120 degrees (obtuse).
