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.
Interior angles: 120 degrees Exterior angles: 60 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.
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.
