A shape that has 120-degree angles is a regular hexagon. In a regular hexagon, all six angles are equal, and each measures 120 degrees. Additionally, certain irregular shapes or polygons can also have 120-degree angles, but the regular hexagon is the most common example.
The four-sided shape with two 70-degree angles and two 110-degree angles is a trapezoid. This shape has one pair of opposite angles (the 70-degree angles) that are equal, and the other pair (the 110-degree angles) also equal. The angles sum up to 360 degrees, which satisfies the requirement for a quadrilateral.
make 120° when they are coplanar.
All the interior angles in a hexagon are 120 degree's, making them obtuse angles.
regular hexagon angles = 120 degrees

120 degree interior angles.
Supplement angles = 180° So 180° - 120° = 60° Complementary angles = 90°
A trapezoid, if the angles going around the shape are 90, 90, 120, 60.
It is an isosceles triangle.

3 angles
A triangle has only three angles and they sum to 180 degrees.
The shape of arsenic pentachloride (AsCl5) is trigonal bipyramidal. In this molecular geometry, the arsenic atom is at the center, with five chlorine atoms positioned around it: three in a plane at 120-degree angles and two above and below this plane at 90-degree angles. This arrangement minimizes electron pair repulsion according to VSEPR theory.
Interior angles: 120 degrees Exterior angles: 60 degrees
