# Geometry Glossary of terms Starting with E-F

This Geometry Glossary defines words starting with E or F.  Use the colored tabs to the right, to access the other definitions in this complete geometry dictionary.

A good geometry glossary is essential to an elementary students success in geometry.  There is nothing more frustrating for a student to get stuck on a math question simply because of an unclear understanding of a word or phrase.  And there is nothing more frustrating for a parent to know the word, but being unable to explain it in a clear fashion for their child.  Eliminate all these problems with this great geometry dictionary.

Simply click on the tabs to find the math definitions you are looking for.  This resource, online is entirely free.  However, if you would like to have a physical copy at home, off-line, for your student to have easy access to, please consider purchasing the e-book - Kindergarten to Sixth Grade Geometry Dictionary.For just \$5.95 - it is excellent value!

Endpoint: The point denoting the end of a line segment.   Equation: This is a mathematical statement containing an equals sign showing that two expressions have the same value.   Equiangular: A shape that has all angles equal.   Equilateral Triangle: A triangle whose sides are all the same length.   Euler's formula: For any convex Polyhedrons surface Euler's Formula states: V - E + F =2 where V,E,F are Vertices, edges and Faces.   Exterior angles: The angle formed on the outside of a polygon, when one side is extended.   Face: The flat surface of a three dimensional shape.   Flat:  Having no depth.   Flip: To 'turn over'.  It is the term to describe a geometric transformation.  Formula: A rule, usually containing symbols (as it is true for all cases) and describes the relationship between quantities.
