A pentagon.
A home plate on a baseball field
The baseball term diamond is in reference to the object you would see if you drew a line from home plate to first base, first base to second base, second base to third base, and third base to home plate. Each of these lines would be the same length (90 feet), therefore, the object would look like a square if you were sitting down the left field or right field lines. But if you were sitting in center field or behind home plate, the object would look like a diamond. A diamond is really a square turned on it's side.
By running around the bases and touching Home plate just like baseball
The Pentagon in Washington is obviously shaped like a pentagon. Black shapes on soccer balls, some road signs and the home plate on a baseball field are all pentagonal shaped objects.
It is a pentagon, but not a regular pentagon- it is shaped like home plate for baseball or softfball.
Softball Field LayoutA softball field is the same as a baseball field. They're practically the same sport. They have a few minor differences like how they pitch and how big the ball is, but they're almost the same. The fields are different because unlike a baseball field, a softball field has no grass in the infield. the softball field mound will be closer than a baseball field mound.the softball field is in a diamond shape with 3bases and a home plate at the corner inside the diamond is all sand and behind the bases there is also some sand after the sand there is an outfield which is all grass.there is also 2 fowl line that go from the left and right side corners of the home plate to the fence in the outfield (usually).-k1956
The dimensions of a baseball field are laid out in the Official Baseball Rules. The key elements are:Bases 90 feet apartPitcher's mound 60' 6" from Home PlateOutfield dimensions are "preferably" 325 feet or more along the foul lines from Home Plate and 400 feet or more from Home Plate to the center field wall. Like hockey rinks, there are subtle variations between fields and some of these distances, as well as the actual configuration of the outfield wall, vary.Another 60 feet from Home Plate to the wall or fence behind it, and at least 60 feet between bases and foul territory is required for a professional layout.While the infields are a standard size, these outfield and foul territory dimensions give adequate room to play a game that is a combination of speed and skill. The dimensions have been very close to these since the 19th century.The field is smaller than cricket grounds and the foul lines and home plate form a "wedge" that is surrounded by fans, (unlike cricket, where most of the action takes place in the center of the pitch at the farthest point from the fans).

When playing baseball, the home base is the shape of a pentagon. Meaning that it has a total of five sides.
A baseball actually does not have specific dimensions like a basketball court or football field. It would depend on the stadium itself. Here are the approximate dimensions for an average field: 90 ft. from base to base 60 ft. from pitchers mound to home plate 320 ft. to left field wall 375 ft. to left center 400 ft.to center 375 ft. to right center 330 ft. to right
