Graph minor theory

Shallow minor

In graph theory, a shallow minor or limited-depth minor is a restricted form of a graph minor in which the subgraphs that are contracted to form the minor have small diameter. Shallow minors were introduced by , who attributed their invention to Charles E. Leiserson and Sivan Toledo. (Wikipedia).

Central Angles, Circle Arcs, Angle Measurement, Major Arcs vs Minor Arcs, Chords - Geometry

This geometry video tutorial provides a basic introduction into central angles, circle arcs, and angle measurement. It explains the difference between a major arc and a minor arc. A central angle always form a minor arc which is less than 180 degrees in angle measure. The major arc is g

What is the measure of a major arc in terms of a minor arc

Learn how to solve problems with arcs of a circle. An arc is a curve made by two points on the circumference of a circle. The measure of an arc corresponds to the central angle made by the two radii from the center of the circle to the endpoints of the arc. The measure of the angle on a c

What is the definition of a secant line

Learn the essential definitions of the parts of a circle. A secant line to a circle is a line that crosses exactly two points on the circle while a tangent line to a circle is a line that touches exactly one point on the circle. A chord is a line that has its two endpoints on the circle.
