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.
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
3 angles
A triangle has only three angles and they sum to 180 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.
make 120° when they are coplanar.
It is an isosceles triangle.
All the interior angles in a hexagon are 120 degree's, making them obtuse angles.
regular hexagon angles = 120 degrees
3 angles
A triangle has only three angles and they sum to 180 degrees.
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.
Interior angles: 120 degrees Exterior angles: 60 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.
