Antiprism Definition
In geometry, antiprism shapes like a prism but having two end nodes, also known as identical polygons, twisted and connected with a chain of triangles.
Or in simple words, antiprism is determined as the classes or subgroups of prismatoids.
For instance, an octagonal antiprism is shown in the below diagram:
Note:
If you want to know about Apex, you can use our Apex Definition.
You can observe that this octagonal antiprism is combined with two identical parallel octagons. One is twisted, triangles join them.
To calculate the twist in antiprism, you have to divide 180° with the number of sides observed in shape.
Below is a square antiprism diagram, having a twist at 45° (180°/4 = 45°).
