Two: a straight line and a curved line.
One. The line of symmetry for a 180 degree arc (a semicircle) is the line that bisects the arc.
A semicircle has 180 degrees
180x2= 360 degrees
None A semicircle is the shape of a protractor (or half a pizza). It has one straight side and one longer curved edge.
A semicircle.A semicircle.A semicircle.A semicircle.
Semicircle has four syllables.
One is Anticline, which is a semicircle that is like a hill but stop in the middle or the way down. A Syncline, is a semicircle with pressure at both sides. A Monocline, is a semicircle that goes flat with pressure
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.
