A ray in math is a part of a line that has one end point
Transformation in maths is when you shift a point or multiple points in terms of it's original point. Ie if you were to shift the point (2;1) about the x axis the transformed point would be (-2;1).
A ray in math begins as a point (or dot, in laymans terms) with a straight arrow coming from it.
It looks like nothing because it is too small. A point is an object which has a location but has no size.
I assume you mean curve touching? It means that two or more curves intersect at a single point (tangent point).
its somthing that's in math * * * * * Given that the question asked what it meant in MATH terms, the answer is extremely illuminating! A vertex (plural vertices), is a point where two or more lines (edges) of a shape meet. A more common word for vertex is corner.
On a coordinate graph, the origin is the point where the X axis and the Y axis intersect. That is the point where X=0 and Y=0.
principal(in terms of math)- the amount you borrow or deposit
Variable and vertical angles are math terms.
A ray looks like this: •----------------> One end point, and an endless line going the other way.
A math expression is a collection of math terms
