One. The line of symmetry for a 180 degree arc (a semicircle) is the line that bisects the arc.
180x2= 360 degrees

an ovalish shape, like this () Or perhaps a semicircle.
If the semicircle is placed on 1 side of the rectangle:Find the total perimeter(circumference) of the side opposite to the one with the semicircle's base and the 2 sides perpendicular to the semicircle's base.The formula for circumference of a circle is 2πr.Thus for the semicircle we will take the circumference as πr.Find the sum of 1st and 2nd points. This is the final answer.
minor arc
The shape that has one curved side and two straight sides is a semicircle. A semicircle is a two-dimensional shape that is half of a circle, with one curved side and two straight sides that connect at the endpoints of the curved side. The curved side of a semicircle is a semicircular arc, while the two straight sides are diameters that intersect at the center of the circle from which the semicircle is derived.

there are two angles
One. The line of symmetry for a 180 degree arc (a semicircle) is the line that bisects the arc.
No, a semicircle is not a quadrilateral
