Points, Lines, and Planes
A straight path that has no thickness and extends forever.
What is a line ?
A figure formed by two rays, or sides, with the common endpoint, called the vertex.
What is a Angle ?
The part of a conditional statement following the word "if".
What is a Hypothesis
A triangle with one right angle.
What is a Right Angle ?
A perpendicular segment from a vertex of a line to the opposite side.
What is an Altitude of a Triangle ?
The point that bisects, or divides, the segment into 2 congruent segments.
What is a midpoint ?
A angel formed by two opposite rays and measures to 180 degrees.
What is a Straight Angle/Supplementary Angles ?
The part of a conditional statement following the word "then".
What is a Conclusion ?
A triangle with all unequal sides.
What is a Scalene Triangle ?
The point of congruency of the 3 perpendicular bisectors.
What is a Centroid of a Triangle ?
Two rays that have a common endpoint and form a line.
What is Opposite Rays ?
A ray that divides and angle into 2 congruent angles.
What is a Angle Bisector ?
A statement formed by exchanging the hypothesis and conclusion.
What is a Converse Statement ?
A triangle with 2 sides with equal length.
What is an Isosceles Triangle.
3 or more lines that are indirect at one point.
What is Concurrent ?
A statement that is accepted as true without proof.
What is a postulate ?
The set of all points outside the angle.
What is Exterior of an Angle ?
The statement formed by negating the hypothesis and conclusion.
What is an Inverse Statement ?
A triangle with 3 congruent angles.
What is an Equiangular Triangle ?
The same distance from 2 or more objects.
What is an equidistant ?
Any ray, segment, or line that intersects a segment at its midpoint. It divides the segment into 2 equal parts at its midpoint.
What is a Segment Bisector ?
Two angles that are in the same plane with a common vertex and a common side, but no common interior points.
What is Adjacent Angles ?
A statement formed by both exchanging and negating the hypothesis and conclusion.
What is a Contrapositive Statement ?
What is the theorem that states: two angles in one triangle are congruent to two angles in another triangle, then the third pair of angles must also congruent.
What is Third-Angles Theorem ?
A set of points that satisfy the given condition.
