# What are the geometry vocabulary terms?

there is a *TON* of geometry vocab terms. so i hope i can

help by telling you the ones that i learned freshman year in

highschool. these are in the order that we learned them:

**conditional** - statement that can be written in

"if...then" form.

ex: if a car is a corvette, then it is a Chevrolet

ex converse: if a car is a Chevrolet, then it is a corvette

ex counterexample: camaro? impala? Monte Carlo?

**adjacent angles** - two angles that are side by side

**postulate** - statements assumed to be true

**theorems** - statements that have been proven to be

true

**polygon** - enclosed plane figure formed with three or more

segments such that each one intersects the other at its

endpoint

**transversal** - a line, ray, or segment that intersects two

or more coplanar lines, rays or segments, each at a different

point

**skew lines** - lines that are never parallel and never

intersect

**pre-image** - original position of a figure in a plane

**image** - new position of a figure in a plane

**rotation** - transformation that moves a geometric figure

about a point, known as the turn center

**reflection** - transformation in which a line of reflection

acts as a mirror, reflecting points to their images

**probability** - ratio that compares the number of

"successful" outcomes to the number of possible outcomes

**circumference** - distance around the area of a circle

**net** - flat figures that can be folded to enclose a

particular solid figure

**magnitude of a vector** - length of a vector arrow

**vector** - a mathematical quantity that has both direction

& magnitude

**resultant** - sum of two vectors

**fractal** - look the same close up as they do far away

**right angle -** a 90 digree angle

these aren't all of them. and i didnt include the theorems &

postulates. i would recommend looking in the back of a text book in

the glossary or asking your teacher if they have a math dictionary

or something like that. but i hope i could help!!!
