Ignore?
angles
The amount of turning between two lines meeting a common point.
vertex
The point where two sides meet. (Shared end points of the line segments of a polygon.)
right angle
An angle that is 90 degrees (It makes a square in the corner).
Acute Angle
An angle that measures LESS than 90 degrees.
abtuse angle
an angle with measure between 90 and 180
straight angle
An angle that measures 180 degrees
Postulate
A statement that does not have to be proven true
D is in the interior of angle ABC and only if m<ABD + m<DBC = m<ABC.
bisect
To divide into two equal parts
Angles that are next to each other. They share a vertex and a common side.
Vertical Angles
Angles opposite one another when two lines intersect.
Congruent
A plane figure with the same size and shape.
linear pairs
formed by two adjacent angles that equal 180
suplimentary
180 degrees
complimentary
angles with the sum of 90 degrees
Perpendicular lines
lines in a plane that intersect to form 4 right angles
parallel lines
2 lines that never cross/intersect and stay the same distance apart
skew lines
Non coplanar lines that aren't parallel or intersecting
parallel planes
planes that do not intersect
transversal
A line that intersects two or more lines.
alternate interior angles
Angles that lie within a pair of parallel lines and on opposite sides of a transversal; congruent
alternate exterior angles
lines on different sides of the transversal, but on the outside of the lines cut by the transversal
consecutive interior angles
..., If two parallel lines are cut by a transversal, then each pair of consecutive interior angles is supplementary
corresponding angles
Angles that have the same relative positions in geometric figures.
skew
they have no relationship
Integer
The set of whole numbers and their opposites.
positive number
all the numbers greater than 0, on a horizontal number line to the right of 0, and all numbers above the 0 on a vertical number line
negative numbers
-amounts owed
same signs
