What is reflexive?
The space between two intersecting lines or rays.
What is an angle?
A line that crosses two or more coplanar lines.
What is the transversal?
SSS
What is Side-Side-Side?
figures that have congruent angles and proportional sides
What is similar?
A statement that has not yet been proven.
What is a conjecture?
Lines in the same plane that never intersect
What are parallel lines?

An idea that is assumed to be true.
What is a postulate?
Angle whose measure is 90 degrees
What is a right angle?
the angles occupy the same relative position at each intersection
What are corresponding angles?
angles formed from two intersecting lines that are congruent to one another
What are vertical angles?
sliding a figure to map it to another congruent figure
What is a translation?
The if part of a conditional statement.
What is a hypothesis?
Multiplying each data point by its weight and summing the products.
What is a weighted average?
the angles lie on opposite sides of the transversal AND are both outside the two lines.
What are alternate exterior angles?
the longest side in a right triangle, always across from the right angle
What is the hypotenuse?
turning a figure to map it to another congruent figure
What is a rotation?
