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.

Any line through a circle has reflective symmetry about the radius that is at right angles to it.
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 circle does not have any angles.
facts about a semi circle
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 .
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.
no, circles don't have any angles!
