In a circle, it is argued that there are either no corners, or infinitely many, depending upon the depth of the mathematics involved.
Given that a semi-circle is half a circle, then the arc must have either 0/2 = 0 or infinity/2 = infinity corners.
Where the arc connects with the diameter, there are unquestionably two corners, so the two values are:
0+2=2 or infinity+2=infinity
2 or infinity
None because it has 1 straight side and no angles
180º degrees.

One. The line of symmetry for a 180 degree arc (a semicircle) is the line that bisects the arc.
A semicircle has 180 degrees
None because it has 1 straight side and no angles
an ovalish shape, like this () Or perhaps a semicircle.
Semicircle has four syllables.
Well, isn't that a happy little question! A shape with 2 square corners is called a rectangle, my friend. It's like a square, but with two sides longer than the other two. Just imagine all the beautiful landscapes you could create with rectangles in your paintings!

No, a semicircle is not a quadrilateral
Semicircle
The possessive form is semicircle's.
