DILATIONS, SIMILARITY AND TRIG
This is the term used to represent the degree to which an object grew or shrunk
What is the scale factor?
Two parallel lines will have the same kind of this
What is slope?
The first note card of the unit: "All radii are" this
This quadrilateral has 4 congruent sides and 3 right angles
What is a square?
This is a popular trap in Area and Volume problems; instead of the radius, they'll give you this
What is the diameter?
This is a catchphrase that helps students remember their trig ratios
What is SOHCAHTOA?
A rather tedious way to find the length of a line segment on the coordinate grid is to use this formula, derived from the Pythagorean theorem
What is the distance formula?
To describe the measure of a central angle and the measure of the arc it creates, you would probably use this word
What is equal?
To prove this kind of quadrilateral, we only need to show that it has 3 right angles
What is the rectangle?
The 6th law of the Geometry Regents urges you to do this, given great emphasis by repeating the same word 3 times in a row
What is read, read, READ?
To prove two triangles are similar, you first plan of attack is to show they have this
If 3/4 is a slope, then -4/3 would be a perpendicular slope because it is known as this
What is a negative reciprocal?
What is a right angle?
To prove a quadrilateral is a parallelogram, we must show that it has this
What are two sets of opposite parallel/congruent sides?
This is Mr. Carpenter's favorite baseball team
What are the New York Mets?
If you have the adjacent side and want the hypotenuse, you should use this trig ratio
What is cosine?
When we are creating an equation of a line using a slope and a point, we will use this form (which has a very fitting name)
What is point-slope form?
The inscribed angle isn't the only angle that's half of the arc it creates, the angle made between these two types of lines will be as well
What is the chord and tangent?
The only 2 quadrilaterals to have perpendicular diagonals are the square, and this
What is the rhombus?
Out of 80 total credits, this is the "magic number" of credits you need to pass, which equates to only 16 multiple choice questions!
What is 32?
This theorem states that a triangle with a parallel line drawn inside of it creates side lengths that are proportional to one another
What is the Side Splitter Theorem
To check whether a series of rigid motions involves a rotation or a reflection, we need to see if the coordinates have the same kind of this, the same thing you probably did before joining the STEM Academy
What is orientation?
This formula helps us find the measure of an outside angle formed by 2 secants
What is (big arc) - (small arc) / 2?
The only quadrilaterals that always have congruent diagonals are the square, the rectangle, and this
What is the isosceles trapezoid?
Given a right triangle with an altitude drawn, this formula involving its altitude, a, and the two side lengths it intersects, x and y, is always true
What is a2=xy?
