point
A dot.
Point
Use a protractor, or computer software such as GeoGebra (available for free).To draw an an angle of specified measure with a protractor:Draw a straight linePlace a dot at one end of the line. The dot represents the vertex of the angle.Place the center of the protractor at the vertex dot and the baseline of the protractor along line you drew (an arm of the angle).Find the required angle on the scale and then mark a small dot at the edge of the protractor.Join the small dot to the vertex with a ruler to form the second arm of the angle.Label the angle with capital letters.
Dot Product:Given two vectors, a and b, their dot product, represented as a ● b, is equal to their magnitudes multiplied by the cosine of the angle between them, θ, and is a scalar value.a ● b = ║a║║b║cos(θ)Cross Product:Given two vectors, a and b, their cross product, which is a vector, is represented as a X b and is equal to their magnitudes multiplied by the sine of the angle between them, θ, and then multiplied by a unit vector, n, which points perpendicularly away, via the right-hand rule, from the plane that a and b define.a X b = ║a║║b║sin(θ)n

A city, (though not a major one as a major city is represented with a slightly larger dot.)
International Morse ' Q ' : _ _ . _
A circle with a straight line through it, usually at an angle, and often with a small dot where the centre of the circle would be (also on the line, to clarify that the line does go through the centre).
small to large town or a small city

A dot.
The letter E is represented by a single dot when using Morse Code.
