A vertex angle refers to the angle that is formed by the two lines crossing at a vertex. When asked for a vertex angle, the intended query is typically for the size of the angle in degrees or radians.
A vertex is the result of two non-perpendicular lines intersecting, often forming a corner of a shape. For example, a square has four vertices due to having four sides and four corners. The angle of a vertex is measured on the inside of the shape. For a square, the angle would be measured between two connected sides, which would always be 90 degrees.

Full Answer >A protractor is an inexpensive math tool used to measure the sharpness of an angle in a geometric shape. Reading a protractor is fairly simple.
Full Answer >Two rays that meet at a common endpoint are called an angle in geometry. In an angle, the rays are its sides and the endpoint is the vertex.
Full Answer >An angular unconformity is a geological phenomenon where an older layer of rock sits directly beneath a much younger layer of rock because the older layer was forced up at an angle, eroded, and younger rock deposited on top of it. An angular unconformity only stays constant for a relatively short distance into a rock face. Digging horizontally into the older rock reveals younger angled layers.
