Coordinate Geometry
These are lines in a plane that never cross.
This requires three pairs of congruent sides.
What is the SSS Congruence Theorem?
This is the ratio of the lengths of the opposite leg of a right triangle and the adjacent leg of that triangle.
What is the tangent?
This is the formula for the circumference of a circle.
What is C = 2 times pi times r?
This transformation is also known as a slide.
What is a translation?
This is the ratio of the change in y to the change in x.
What is the slope?
This means that a segment (or angle) of one triangle must be congruent to a corresponding segment (or angle) of a congruent triangle.
What is CPCTC?
This trigonometric ratio does not involve the length of the opposite leg of the right triangle.
What is the cosine?
This is half of a sphere.
What is a hemisphere?
This type of transformation preserves segment length and angle measure.
What is a rigid motion?
This is the slope of a line perpendicular to a line with a given slope.
What is the negative (or opposite) reciprocal?
This theorem requires an included angle.
What is the SAS Congruence Theorem?
To find the area of this shape, multiply two of its sides and the sine of the included angle and then divide by two.
What is a triangle?
This shape has a volume of pi times r squared times h.
What is a (right circular) cylinder?
This transformation changes the orientation of a shape (clockwise to counterclockwise or vice versa).
What is a reflection?
This formula is just the Pythagorean Theorem in disguise.
What is the distance formula?
This theorem requires a right triangle.
What is the (R)HL Congruence Theorem?
This acronym is a mnemonic device that can help you set up a trigonometric equation.
What is SOHCAHTOA?
This is represented by the D in the formula D = M/V.
What is density?
This is another name for a 180 degree rotation.
What is a point reflection?
This formula involves finding the average x-coordinate and the average y-coordinate.
What is the midpoint formula?
This is a convincing logical argument, sometimes made in two columns.
What is a proof?
This is equal to the sine of 40 degrees.
What is the cosine of 50 degrees?
What is a square pyramid?
This is the what we might call the shape before it gets transformed.
What is the pre-image?
