The Definition of an Angle The Meaning of Angle or Definition of an Angle. Math. Angles are formed by two rays that begin at the same point or share the same endpoint. The angle measures the amount of turn between the two arms and is usually measured in degrees or radians. Where the two rays intersect (come together to meet) is called the vertex.

- Delta in math is generally symbolized as the triangle. Can mean, variation of a variable or function. However its meaning changes depending in the context.elta is a symbol that denotes a change in something. In physics the delta-v is used to calculate the change in velocity, or change in velocity over time.

- explain what the 'tangent of theta' means. Draw and label a diagram to help with your explanation. The conventional way to define the trig functions is to start with an acute angle $\theta,$ that is an angle with measure $\theta$ between $0$ and $90$ degrees. You then draw a right triangle having one angle with measure $\theta$ degrees and label the three sides. The longest side of the triangle is called the hypotenuse, the side opposite the angle $\theta$ is called the opposite side, the third side is called the adjacent side.
