vertex | the common endpoint |
volume | a measure of the amount of space enclosed by a three dimensional figure. |
adjacent | common vertex and side with no common interior points (nothing overlaps) |
linear pair | adjacent angles that are formed by opposite rays. |
vertical angles | two nonadjacent angles formed by tow lines (always form a "X") |

inductive reasoning | use number of specific example to arvie at a conclusion. |
conjecture | a concluding statement. |
counter example | an example that proves a statement is false . |
commpound statement | joined by "AND.OR" |
conjunction statement | joined by "AND" |
disconjunction statement | joined by "OR" |
negation | not "P" is the negation of the statement "P". |
conditional statement | a statment that can be written in "IF-THEN FORM". |
hypothesis | the phrase of a conditional statement that immediatley follows the word "IF". |
conclusion | the phrase of a conditional statement that immmediatley follows the word "THEN". |
converse | formed by exchanging hypothesis and conclusion. |
inverse | formed by negating both the hypothesis and the conclusion. |
contrapositive | formed by negating both parts of the converse. |
PARALLEL LINES | NEVER INTERSECT (CROSS) IN THE SAME PLANE (COPLANAR). |
TRANSVERSAL | A LINE THAT GOES THROUGH TWO OR MORE LINES AT TWO DIFFERENT POINTS. |
SKEW LINES | DO NOT INTERSECT AND ARE NOT COPLANAR (NOT ON THE SAME PLANE) |

ALTERNATE EXTERIOR ANGLES | NONADJACENT EXTERIOR ANGLES THAT LIE ON THE OPPOSITE SIDE OF THE TRANSVERSAL. |
CONSECTIVE INTERIOR ANGLES | INTERIOR ANGLE ON THE SAME SIDE OF THE TRANSVERSAL. |
CORRESPONDING ANGLES | LIE ON THE SAME SIDE OF THE TRANSVERSAL ON THE SAME SIDE OF THE LINES. |
