Dilations
This is what the subscript of 2 represents in D2
What is the scale factor?
This is what you'll get the value of when you divide the corresponding sides of the image with the pre-image
What is scale factor?
This is the mnemonic device used to easily define the three main trigonometric ratios
What is SOHCAHTOA?
These are the trigonometric co-functions.
What are sine and cosine?
This theorem can be used to find distance between two points or the missing side length of a given right triangle
What is the Pythagorean Theorem?
This is what you calculate from the center of dilation to a given vertice of a figure
What is the rate of change/slope?
This is created by putting all corresponding sides in proportion to one another.
This is the appropriate trigonometric function to use when theta is given with a value for the hypotenuse and the side found next to theta
What is cosine?
This is how we describe the relationship between A and B given sinA = cosB.
This is the formal name for when A = B and B = C then A = C
What is the Law of Syllogism?
What is both similar and congruent?
These are created from extended ratios and are often used to solve for missing side lengths among similar figures
What are proportions?
When labeling your right triangle the opposite and adjacent sides are dependent on this value
What is your given theta?
This is the length of the hypotenuse side given that sinA = cosB = 4/5
What is 5 units?
Rigid motions do this
What is preserve size and shape of figures?
This is how many equal pieces a line segment is cut into given that there is a point that splits it into a ratio of 4:9
What is 13 equal pieces?
This is what makes proportions created from similar right triangles a special case
What is the repeating mean values or either the length of the altitude or the length of one of the legs?
An angle of depression and an angle of elevation are said to have this relationship
In a 30-60-90 triangle with a scale factor of 4, this is what would sin30 = cos60 equal to as a ratio of side lengths
What is 4/8 or 1/2?
This is the sum of all interior angles of a regular nonagon
What is 1,260 degrees?
What is 17.5/24.5?
Daily Double! Everyone plays. If ABC ~ DEF and angle A is equivalent to 78 degrees, angle C is equivalent to 31 degrees, then this is the measurement of angle E.
What is 71 degrees?
This is the sequence of buttons you hit to get your calculator in the correct mode to then solve for an unknown theta
What is Mode, Down 2x, Enter, 2nd, Mode, 2nd, Appropriate Trig Function?
Daily Double! Everyone plays. This is the appropriate value of x in the following sin(4x + 5) = cos(x2)
What is 5?
Daily Double! Everyone plays. This is the family relationship between all quadrilaterals
What is (picture of Quad Family Tree)?
