 3rd side (hint)
conjecture

u think a statement is true but havent proven it yet



inductive reasoning

the process u go through to find the conjecture or counter example



undefied terms

understanding what the term is but not the dictionary definition



point

establishing a thing, no size, capital letters (A,B,C)



line

a set of points made straight that goes on forever



plane

wto dimensionals ex. floor, wall, ceiling



collinear

on the same line



coplanar

on the same plane



line segment

part of a line



ray

goes only in one direction



opposite rays

two ray that when put together make a line



intersect

two lines or two rays meet, intersection
two lines intersect at a point two planes intersect at a line 


postulate or axiom

statements we except as true, but hard to prove



coordinate

a point on a line with a number for every point on a line



distance or length

the absolute value of the difference between the coordinates of the points



congruent segments

the length of two segments are the same



angle

two rays with the same endpoint



vertex

the common initial point



sides of angle

the rays that make up that angle



congruent angles

angles with the same measure



postulate

measure of an angle each ray is accociated with a real number, then u find the absolute value



acute angle

less than 90 more than 0



right angle

90



obtuse angle

more than 90 less than 180



straight angle

180



adjacent angle

two angles that share a common ray

a


midoint

point in the middle of a line segment



bisect

cut in half



segment bisector

whatever we use to cut it in half...line,plane..ect



compass

a tool we use to draw circles



straight edge

a tool used to make a line that doesnt have any markings



construction

geometric diagram in which we use specific tools



midpoint formula

x1+x2/2, y1+y1/2



angle bisector

the ray that cuts the angle in half



supplementary angles

angles that add up to 180



complementary angles

angles that add up to 90



vertical angles

sides form to pairs of opposite rays



linear angles

two angles that make a line

angles(points) that make a line is .......l
