Contrapositive "if A, then B (A -> B)" - correct answer If not B, then not A (~B -> ~A)
Converse "if A ,then B (A -> B)" - correct answer If B, then A (B->A)
Inverse "if A , then B (A -> B)" - correct answer If not A, then not B (~A-> ~B)
Theorem - correct answer a statement that has been proven
corollary - correct answer a statement that makes sense based on a theorem
postulate/axiom - correct answer a statement that is accepted as true without proof
common notion - correct answer A statement that is not officially defined but that is understood to be common sense.
endpoint - correct answer A point at either end of a line segment or arc, or a point at one end of a ray.
midpoint - correct answer a point that divides a segment into 2 congruent segments (AB+ BC=AC)
Segment Addition Postulate - correct answer A postulate stating that if AC+ BC= AB then point C is between points A and B so AC+ CB= AB
vertex - correct answer endpoint of an angle
zero angle - correct answer A ray/angle that measures 0 degrees
straight angle - correct answer an angle that measures exactly 180 degrees
right angle - correct answer an angle that measures 90 degrees
acute angle - correct answer an angle that measures less than 90 degrees
obtuse angle - correct answer An angle that measures more than 90 degrees but less than 180 degrees
angle bisector - correct answer a ray that divides an angle into two congruent angles
adjacent angles - correct answer Two angles that share a side and vertex
supplementary angles - correct answer two angles whose measures have a sum of 180 degrees linear pair - correct answer a pair of supplementary angles that are adjacent
complementary angles - correct answer two angles whose measures have a sum of 90 degrees
congruent - correct answer Having the same size and shape. ≅
Angle Addition Postulate - correct answer if point C lies in the interior of angle AVB then the measure of angle CVB is the measure of angle AVB
alternate interior angles - correct answer 2 angles formed by a transversal that intersects two parallel lines. The angles are on opposite sides of the transversal and inside the parallel lines
angle of incidence - correct answer The angle between a ray of light meeting a surface and the line perpendicular to the surface at the point of contact.
angle of reflection - correct answer The angle between a ray of light reflecting off a surface and the line perpendicular to the surface at the point of contact.
consecutive interior angles - correct answer 2 angles formed by a transversal that intersects two parallel lines. The angles are on the same side of the transversal and are inside the parallel lines.
corresponding angles - correct answer 2 nonadjacent angles formed on the same side
of a transversal that intersects two parallel lines, with one angle interior and one angle exterior to the lines.
Law of Reflection - correct answer A law stating that the angle of incidence is congruent to the angle of reflection.
skew lines - correct answer Lines that are not in the same plane. Skew lines do not intersect, and they are not parallel.
transversal - correct answer A line, ray, or segment that intersects two or more coplanar lines, rays, or segments at different points.
Corresponding Angles Theorem - correct answer If a transversal intersects 2 parallel lines, then corresponding angles are congruent
Alternate Interior Angles Theorem - correct answer if 2 parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent
rigid motion - correct answer a transformation applied to a figure that doesn't change its shape or size at any time
Contrapositive "if A, then B (A -> B)" - correct answer If not B, then not A (~B -> ~A)
