Math Definitions - Letter I


Definition of Intersection

Definition of Intersection

An intersection is a point that is common to two lines or curves.

Note: we usually refer to this point as a "point of intersection" or an "intersection point".

In the picture, the orange line and the blue curve intersect at the red dot, where they cross over. The red dot shows their point of intersection.


The aim of this dictionary is to provide definitions to common mathematical terms. Students learn a new math skill every week at school, sometimes just before they start a new skill, if they want to look at what a specific term means, this is where this dictionary will become handy and a go-to guide for a student.
