What is the formula for the area of a triangle?
A = (1/2)bh
What is an angle that is larger than 90 degrees called?
An obtuse angle.
Slope-intercept form is:
y = mx + b
The Pythagorean Theorem only works with this kind of triangle.
What are right triangles?
How old is Mr. Ao?
23
What is the formula for Pythagorean Theorem?
a^2 + b^2 = c^2
Complementary angles add up to how many degrees?
90 degrees.
Is this a linear equation?
y = (1/2x) + 47
No; x has an exponent of -1.
This is the name for the longest side of a right triangle.
What is a hypotenuse?
Where is Mr. Ao from?
NEW YORK THE GREATEST STATE IN THE UNION BABY!
What formula is used to find slope when given two coordinates?
Angle A is 57 degrees. Angle B is 101 degrees. If angles A, B, and C are supplementary, what is the measure of angle C?
A + B + C = 180
57 + 101 + C = 180
C = 180 - 101 - 57 = 22
What kind of line has an undefined slope?
A vertical line.
The mathematician, Pythagoras, was from this country.
What is Greece?
What instrument did Mr. Ao play in marching band?
The bass drum.
What is the formula for the volume of a sphere?
V = (4/3)*pi*r^3
How can you use angles to prove triangles are similar?
If triangles share two angles of the same value, the third angle of each triangle is also the same.
In what situation would a system of linear equations have infinite solutions?
When the equations both make the same line.
If a right triangle has legs of length 5 and length 12, how long is the hypotenuse?
13
What sport did Mr. Ao play as a child?
Roller Hockey.
What is the formula for scale factor/dilation?
|PQ| = r|P'Q'|
What are the three angle pairs we discussed this year?
Corresponding, vertical/opposite, and alternate interior angles.
How many solutions does this system of linear equations have?
y = 6x + 14
20 = 2y - 12x
There are no solutions; these are parallel lines.
If a right triangle has a leg of length 24 and a hypotenuse of length 25, how long is the missing leg?
7
What movie did Mr. Ao go to see on his first date that he can no longer watch?
Frozen.
