A _________statement, symbolized by p q, is an if-then statement in which p is a hypothesis and q is a conclusion
What is A conditional statement?

A transformation that does not alter the size or shape of a figure; rotations, reflections, translations are all rigid transformations.
What is rigid transformation?

To show a Conditional statement is false you must find a.....?
What is Conditional Statement?
200
A ______is a transformation which "slides" a figure a fixed distance in a given direction. In a_____, ALL of the points move the same distance in the same direction.
What is a translation?
300
Part of a line with two end-points
What is a line segment ?
300
Pairs of opposite angles made by two intersecting lines.
What is vertical angle?
300
Symmetry around a central axis, as in a starfish or a tulip flower.
What is radial symmetry ?
300
A________statement is defined to be true whenever both parts have the same truth value. The ______ operator is denoted by a double-headed arrow . The _________ p q represents "p if and only if q," where p is a hypothesis and q is a conclusion.
What is Bi-conditional statement
300
A quantity having direction as well as magnitude, especially as determining the position of one point in space relative to another.
What is a vector?
400
Part of a line with one endpoint, extending infinitely in one direction
What is a ray?
400
Two angles that have a common side and a common vertex (corner point), and don't overlap.
What are Adjacent Angles?
400
When the all the legs of two triangles are congruent we say itś congruent by the criteria...
What is a SSS
400
To form the_______of the conditional statement, interchange the hypothesis and the conclusion. The________ of "If it rains, then they cancel school" is "If they cancel school, then it rains."
What is the converse?
400
A transformation in which a plane figure turns around a fixed center point. In other words, one point on the plane, the center of turn is fixed and everything else on the plane turn about that point by a given angle.
What is a rotation?
500
An infinite Set of points extending infinitely in two directions
What is a line?
500
When two lines are crossed by another line (called the Transversal): The pairs of angles on opposite sides of the transversal but inside the two lines are called...?
What are Alt. Interior angles?
500
Criteria to show that two right angled triangles are congruent by the longest side and one of the other sides
What is HL
500
To form th_______e of the conditional statement, interchange the hypothesis and the conclusion of the inverse statement. The ______of "If it rains, then they cancel school" is "If they do not cancel school, then it does not rain."
What is the contrapositive?
500
A rigid transformation in which the preimage is flipped across a line to create a similar image. Each point of the image is the same distance from the line as the preimage is, just on the opposite side of the line.
What is a reflection?
