What a Year
All Lined Up
Ugh Triangles
Going in Circles
Potent Proofs
100
The name of the unit we are currently studying.
What is Circles & Circumference?
100
This is what is referred to as the steepness of a line.
What is slope?
100
Sine = Opposite over Hypotenuse
Cosine = Adjacent over Hypotenuse
Tangent = Opposite over Adjacent
What is SOH-CAH-TOA?
100
The ratio of pi.
What is circumference divided by diameter?
100
The first step to a formal proof. (Usually)
What is the given?
200
The number of units in the first semester.
What is 8?
200
How a line gets its name.
What are two points on the line?
200
The measures of the angles of a triangle if it is equilateral.
What is 60 degrees?
200
Another name that we can call a diameter. And no it's not double radius.
What is a chord?
200
A proof that is setup into two columns.
What is a formal proof or a two column proof?
300
The number of times Mr. Rodriguez has been absent this year.
What is 1?
300
A line that goes through a circle at exactly 2 points.
What is a secant?
300
When proving triangles congruent we use a lot of 3 letter acronyms except this one. Probably best since it would get you sent to the principals office.
What is SSA?
300
An inscribed angle is half the measure.
What is an intercepted arc?
300
A logical proof that proves something to be true through contradiction.
What is an indirect proof?
400
Often said to correct misconceptions or to redirect students on why something needs to be solved the correct way. Mr. Rodriguez loves saying.
What is "we don't assume" or "we don't assume, we prove"?
400
When two lines have opposite reciprocal slopes we call them this.
What is perpendicular?
400
This is how we got the distance formula. Good thing too, we don't want to always travel in triangles.
What is the Pythagorean Theorem?
400
The two lines shown here.
What are secant and tangent?
400
If BC=CD and AB=BC, then AB=CD.
What is the transitive property of equality?
500
This is the number of units that have focused solely on triangles. We love triangles!
What is 3?
500
The way lines are proven to be parallel. You draw this to make corresponding angles.
What is a transversal?
500
The center of a triangle when you draw all of its perpendicular bisectors. Oh wow you can draw a circle around the triangle with this too!
What is the circumcenter?
500
The equation of a circle with radius 6 with the center at the origin.
What is x^2 + y^2 = 36?
500
When something is proven to always be true through a logical proof. Afterwards it can be considered a rule of math.
What is a theorem?
