Angles
Angles that have the same measure
Congruent angles
Two angles whose measures have a sum of 90 degrees.
Complementary angles
To divide into two congruent parts
An undefined term in Geometry. It names a location and has no size.
Point
The condition within a conditional statement, usually represented as the "if" part
Hypothesis
The common endpoint of the sides of the angle
Vertex
Two angles in the same plane with a common vertex and a common side, but no common interior points
Adjacent angles
The point that divides a segment into two congruent segments.
Midpoint
An undefined term in geometry that is a straight path that has no thickness and extends forever.
Line
The consequence of a conditional statement, usually represented as the "then" part
Conclusion
A figure formed by two rays with a common endoint
Angle
Two adjacent angles that form a straight line
Linear pair
Points that lie on the same line
Collinear
An undefined term in Geometry, it is a flat surface that has no thickness and extends forever.
Plane
The only one among inverse, converse, and contrapositive that always has the same truth value as the original statement
Contrapositive
A ray that divides an angle into two congruent angles.
Angle bisector
Two angles whose measures have a sum of 180 degrees
Supplementary angles
You need 3 non-collinear points to name one
Plane
A part of a line that starts at an endopint and extends forever in one direction.
What is a ray?
For the statement P --> Q, what is the converse?
Q --> P
The following is the definition of what:
If point D is the interior of <ABC then, <ABD + <DBC = <ABC
Angle addition postulate
Opposite and congruent angles formed by two intersecting lines
Vertical angles
An angle between 180 and 270 degrees
Reflex angle
For the statement "if a student eats only ice cream in the dining hall, she'll get sick", what kind of statement is "if a student doesn't eat only ice cream in the dining hall, she won't get sick"
Inverse
