Angles do not have areas because they are not closed shapes.
An angle is a measure of how two lines meet each other. An angle by itself does not have an 'area'.
There is no equivalence. An angle is a measure of rotational displacement. It is formed by two rays (or lines) and does not create an enclosed space. An area is a measure of an enclosed space.
Area of sector/Area of circle = Angle of sector/360o Area of sector = (Area of circle*Angle of sector)/360o
A regular quadrilateral is a square. As to the measure, the answer depends on the measure of WHAT? An angle, a side, the diagonal, area, perimeter, etc.
We can't say how many degrees there are in a sphere, any more than we can say how many feet there are in an acre. Feet are a measure of length, and an acre is an area, not a length. You can't measure an area with a tape measure. Likewise, degrees are a measure of an angle; you can sweep out a circle by swinging a line through an angle of 360 degrees. But you can't sweep out a sphere by swinging a line through some angle, so angle measure won't do to measure a sphere.
the measure of an angle is the degrees of an angle.
you can measure a angle with a protracte.
they both measure the angle in degrees
The measure of the obtuse angle would then be double that of the acute angle.
The measure of the exterior angle.
No cheating!
A solid angle, measured from a vertex, is the ratio between the area subtended by the angle at the vertex and the the square of the distance to the vertex. The unit of measurement is the stradian.
