WebIn mathematics (and more specifically geometry ), a semicircle is a one-dimensional locus of points that forms half of a circle. It is a circular arc that measures 180° (equivalently, π radians, or a half-turn ). It has only one line of symmetry ( reflection symmetry ). WebA degree is a unit of measurement of an angle. One rotation around a circle is equal to 360 degrees. An angle measured in degrees should always include the degree symbol ∘ ∘ or the word "degrees" after the number. For example, 90∘ = 90 90 ∘ = 90 degrees. Example6. Give the degree measure of the angle shown on the circle.
