A semi-circle is a two dimensional shape.

Two: a straight line and a curved line.
semi
add the perimeter of the rectangle, minus the side that'c covered by the semi circle. then, find the circumference of the semi circle [diameter x pi, divided by 2] and addd them together
Semi means half. So there are two semicircles in a 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.
a semi-circle only has one line of symmetry
A semi-circle has one curved edge, which is the arc of the circle, and one straight edge, which is the diameter. Therefore, a semi-circle has a total of two edges.
