It all matters what the inside angles measure up to. If the inside angles measure up to 360 degrees, the shape will tile. If the inside angles do not add up to 360 degrees, the shape won't tile.
Because it is easier to use. If a right angle were to be 100 degrees when you compare it to 90, 90 has a lot more factors than 100. It's probably in the ancient days when people made it like that.
Exterior angles add up to 360 degrees Interior angles add up to 900 degrees
The angles inside any shape with more than 7 sides always add up to more than 1,000 degrees.
A triangle
It all matters what the inside angles measure up to. If the inside angles measure up to 360 degrees, the shape will tile. If the inside angles do not add up to 360 degrees, the shape won't tile.
The four inside angles add up to 360 degrees.

Any shape that you can draw on paper with four straight lines, no matter its size and shape, has four angles inside it that add up to 360 degrees.
Interior angles add up to 540 degrees Exterior angles add up to 360 degrees
Interior angles add up to 720 degrees Exterior angles add up to 360 degrees
all inside angles of a hexagon add up to 720°
The three inside angles add up to 180 degrees.And so do the three outside angles.
