Coordinate Geometry
This is the point (0, 0) on the x-y plane.
What is the origin?
These are statements that you probably have to use in your proof but you still might not get a point for including them.
What are the givens?
This is an object that can be represented by two capital letters with a two-way arrow on top.
What is a line?
This is a triangle with three congruent sides.
What is an equilateral triangle?
In other words, this transformation is a slide.
What is a translation?
This is the change in y over the change in x.
What is the slope?
This is a way to prove two triangles congruent that includes one pair of congruent angles.
What is the SAS Theorem?
This is represented by an upside down T symbol.
What is perpendicular?
This is a set of points that are all equidistant from a given point called the center.
What is a circle?
This type of transformation is not an isometry.
What is a dilation?
This theorem is the basis of the distance formula.
What is the Pythagorean Theorem?
This is a way to prove two triangles congruent that requires the triangles to be right triangles.
What is the RHL Theorem?
This is represented by an equal sign with a tilde right above it.
What is the congruent symbol?
This is a triangle that has 2 or 3 congruent sides.
What is an isosceles triangle?
This is the number of lines of symmetry in a square.
What is 4?
These are lines with negative reciprocal slopes.
What are perpendicular lines?
If these interior angles formed by the transversal are congruent, then the lines are parallel.
What are alternate interior angles?
These lines in a figure have identical arrows on them.
What are parallel lines?
This is a quadrilateral with two pairs of opposite parallel sides.
What is a parallelogram?
This transformation changes the orientation of a figure (clockwise to counterclockwise or vice versa).
What is a reflection?
This is the slope of a vertical line.
What is undefined?
This is the reason that AB = CD implies that segment AB is congruent to segment CD.
What is the definition of congruence?
This is represented by two adjacent letters with no line over them (like AB).
What is the length of a segment?
This a rectangular rhombus.
What is a square?
This transformation requires a center and an angle.
What is a rotation?
