about its radius
a semi-circle only has one line of symmetry
a semi-circle only has one line of symmetry
Just the one and it is its radius when at right angles to the semi-circle's centre
If the central point of the straight line is placed exactly on the middle, and such central point has an axis, it will have a rotational symmetry.
Not really, a line of symmetry is where the shape is identical on both halves. A circle has an infinite number of lines of symmetry. Any line passing through the circle's center is a line of symmetry.
The diameter of a circle is its line of symmetry and the lines can be infinite
The semi circle is a shape which has 1 line of symmetry 1straight side 0 equal length sides 0 parallel sides 2 vertices 0 diagnals
A circle has infinite lines of symmetry, any line going through the center is a line for symmetry.

A triangle with only two of its sides equal. Also a semi-circle or any incomplete circle.
