What are the angles of home plate?
As home plate is a 5 sided base, there are angles needed to form its diamond shape.
There are 3 right angles formed by home plate.
The rear angles of the plate are 45 degrees forming a right angle at the point at the back.
The 2 side edges are vertical from the rear angles joining the top of the plate where the other 2 right angles are formed.
Why is home plate designed as a 5 sided base?
Home plate didn’t always be the 5 sided diamond shape that it is today. Pre 1900, the home plate was the same shape as the other bases.
