alternate exterior angles

Front

pair of angles on the outer side of each of those two lines but on opposite sides of the transversal

Back

corresponding angles

Front

When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles.

Back

Converse of Same Side Interior

Front

If two lines are cut by a transversal and the same side interior angles are supplementary, then the lines are parallel

Back

complementary

Front

when 2 angles are put together they equal 90 degrees (when you compliment Mrs.Dieppa you are right and a right angle is 90 degrees

Back

Transversal

Front

intersecting a system of lines

Back

Segment

Front

a line with 2 endpoints

Back

Reflexive Property

Front

The reflexive property of equality simply states that a value is equal to itself ex: a=a

Back

Transitive Property

Front

If a = b and b = c, then a = c

Back

parallel lines

Front

lines in the same plane that do not intersect

Back

vertical angles

Front

two nonadjacent angles formed by two intersecting lines

Back

adjacent angles

Front

Two angles are Adjacent when they have a common side and a common vertex and don't interlap

Back

Plane

Front

a flat two-dimensional surface that extends infinitely far

Back

Segment Addition Postulate

Front

If B is between A & C, then AB + BC = AC. (basically means: 2 connected segments added together will equal measure of big segment formed by both)

Back

postulate

Front

Postulates are the basic structure from which theorems are derived

Back

Substitution Property

Front

x = y, then x can be substituted in for y in any equation, and y can be substituted for x in any equation.

Back

Converse of Alternate Exterior

Front

If two lines are cut by a transversal and the alternate exterior angles are congruent, then the lines are parallel

Back

Obtuse Angle

Front

It is more than 90° and less than 180°

Back

Angle Addition Postulate

Front

The postulate describes that putting two angles side by side with their vertices together creates a new angle whose measure equals the sum of the measures of the two original angles

Back

Line

Front

a line of points that goes on forever in two directions

Back

Acute Angle

Front

The range of an acute angle is between 0 and 90 degrees

Back

same side exterior angles

Front

Two angles that are exterior to the parallel lines and on the same side of the transversal line

Back

Straight Angle

Front

an angle of 180°

Back

segment bisector

Front

a segment, ray, line, or plane that intersects a segment at its midpoint

Back

Linear Pair

Front

A linear pair of angles is formed when two lines intersect; formed by two intersecting lines; straight equals 180 degrees

Back

Converse of Corresponding

Front

If two lines and a transversal form corresponding angles that are congruent, then the lines are parallel.

Back

Supplementary

Front

when 2 angles are put together they equal 180 degrees

Back

Symmetric Property

Front

we can interchange the sides of an equation and the equation is still a true statement If a = b, then b = a

Back

alternate interior angles

Front

formed when a transversal passes through two lines

Back

perpendicular angles

Front

Two lines that intersect to form right angles

Back

Rights Angles

Front

an angle of 90°

Back

Point

Front

a point is a specific location on a line or graph

Back

same side interior angles

Front

two angles that are on the same side of the transversal and on the interior of (between) the two lines

Back

Midpoint

Front

the middle point of a line segment

Back

Angle bisector

Front

a ray that divides an angle into 2 congruent angles

Back

Ray

Front

Line with one endpoint while other side goes on forever

Back

Theorem

Front

A theorem is a true statement that can be proven

Back

collinear points

Front

points that lie on the same line

Back

Reflex Angle

Front

It is more than 180° but less than 360°

Back

Congruent

Front

shapes that are the same size and shape

Back
