a circle
Triangle, paraellogram(srry if i didnt spell that right...), circle
Any line through a circle has reflective symmetry about the radius that is at right angles to it.
A circle does not have any angles.
no, circles don't have any angles!
a circle
It has no angles because circles are not common shapes. Well they're common but they don't have ANY sides, angles, OR CORNERS!
In a circle no, in a square yes.

facts about a semi circle
An inscribed angle is an angle formed by two chords in a circle which have a common endpoint. This common endpoint forms the vertex of the inscribed angle.The other two endpoints define an intercepted arc on the circle Any angle inscribed in a semi-circle is a right angle. The proof is simply that the intercepted arc is 180 so the angle must be half of that or 90 degrees.
A semi-circle is a 180 degree half circle. A semi-circle does not have any corners. A circle does not have corners either. There are points of beginning and end in a semi-circle. In a circle the point of beginning is the same as the ending point.
it has 2 corners .
no, circles don't have any angles!
The right angle of a right-angle triangle, like all right angles, is 90 degrees or one quarter of 360 (a full circle). All the angles of any triangle will add up to 180 degrees.
