Points, lines, and planes are the building blocks of geometric objects and known as this.
Undefined Terms
Reasoning that is based upon rules (postulates, definitions, etc.) and employs conditional statements is known as this.
Deductive
If two lines form congruent, adjacent angles, then we call them this.
Perpendicular
The sum the degrees of the angles in a triangle is this.
180
A figure where both pairs of opposites are parallel is called this.
Parallelogram
The condition that two points are on the same line.
Collinear
An example used to show that a conditional statement is false
Counterexample
Parallel
This is often confused as way to show triangle congruency, but is actually not a way to do so.
SSA
If the diagonals of a quadrilateral bisect each other perpendicularly, then we can conclude it is this.
Rhombus
The condition that two points, lines, or planes are the same distance relative to another object is called this.
Equidistant
If a conditional statement and its converse are both true, then a statement is known as this.
Biconditional
If two angles formed by a transversal through parallel lines are on the opposite sides of the transversal and the inside of the parallel lines, then they are called this.
Alternate Interior Angles
When two triangles are congruent, we can deduce congruency about their various parts using this notion.
CPCTC
Rectangle
Segment Addition Postulate
If two conditional statements result in the same truth values, then these statements are called this.
Logically Equivalent
A triangle can have at most this many perpendicular sides.
One
If an only if two sides of a triangle are congruent to each other, then we can conclude this by definition.
The triangle is isosceles
This quadrilateral is both a rhombus and a rectangle.
Square
Cogruence
Tautology
If two lines are parallel and cut by a transversal, then the two angles that are on the same side of the transversal and the inside of the parallel lines are called this.
Same Side Interior
The Leg Leg Method for proving congruence of right triangles is a corollary of this postulate.
SAS
If consecutive sides of a quadrilateral are congruent, but opposite sides are not, then we call it this.
