Properties, and Laws and Theorems....O My!!!
100
Has no dimension. It is represented by a small dot.
What is a point?
100
The point on the segment that divides it into two congruent segments.
What is the midpoint?
100
Two lines that lie in the same plane and do not intersect.
What are parallel lines?
100
Two rays that have the same endpoint.
What is an angle?
100
Adding the same number to each side of an equation produces an equivalent equation.
What is the Addition Property?
200
Has one dimension. It extends without end in two directions.
What is a line?
200
A segment, ray, line, or plane that intersects a segment at it's midpoint.
What is a segment bisector?
200
Two lines that intersect to form a right angle.
What are perpendicular lines?
200
The endpoint of an angle.
What is a vertex?
200
Dividing each side of an equation by the same nonzero number produces an equivalent equation.
What is the Division property?
300
Has two dimensions. It is represented by a shape that looks like a floor or wall.
What is a plane?
300
A ray that divides an angle into two angles that are congruent.
What is an angle bisector?
300
A line that intersects two or more coplanar lines at different points.
What is a transversal?
300
The sum of the measures of two angles equals 90 degrees.
What are complementary angles?
300
If two angles are complementary to the same angle, then they are congruent.
What is the Congruent Complements Theorem?
400
Statements accepted without further justification.
What is a postulate?
400
A true statement that follows from other true statements.
What is a theorem?
400
An if-then statement that is formed by switching the hypothesis and the conclusion.
What is a converse?
400
The sum of the measure of the angles is equal to 180 degrees.
What are supplementary angles?
400
If two angles are supplementary to the same angle, then they are congruent.
What is the Congruent Supplements Theorem?
500
The real number that corresponds to a point.
What is the coordinate?
500
Two angles that are not adjacent and their sides are formed by two intersecting lines.
What are vertical angles?
500
A line that intersects a plane in a point and that is perpendicular to every line in the plane that intersects it.
What is a line perpendicular to a plane?
500
Two angles that share a common vertex and side, but have no common interior points.
What are adjacent angles?
500
If the hypothesis of a true if-then statement is true, then the conclusion is also true.
What is the Law of Detachment?
