Pizza slices are not triangles.
They are sectors. A sector is a cut from the center of a circle to any part of its circumference (the curved line of a circle). A slice of pizza would have been a triangle if all three sides were straight lines. However, it is a circular sector because two sides are straight while the third is curved.

Have you heard of a squircle?
Squircles are a hybrid of squares and circles. They are essentially squares with round edges.
However, a squircle is not the same with a rounded square, a lookalike shape with similarly rounded edges. A rounded square still has a bit of that squarish edge even though it is less defined and may be indistinguishable to people who do not know the difference between both shapes. Meanwhile, squircles have smooth circular edges.
