What is the formula for the area of a triangle?

A = (1/2)bh

100

What is an angle that is larger than 90 degrees called?

An obtuse angle.

100

Slope-intercept form is:

y = mx + b

100

The Pythagorean Theorem only works with this kind of triangle.

What are right triangles?

100

How old is Mr. Ao?

23

200

What is the formula for Pythagorean Theorem?

a^2 + b^2 = c^2

200

Complementary angles add up to how many degrees?

90 degrees.

200

Is this a linear equation?

y = (1/2x) + 47

No; x has an exponent of -1.

200

This is the name for the longest side of a right triangle.

What is a hypotenuse?

200

Where is Mr. Ao from?

NEW YORK THE GREATEST STATE IN THE UNION BABY!

300

What formula is used to find slope when given two coordinates?

m = (y2 - y1)/(x2 - x1)
300

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

300

What kind of line has an undefined slope?

A vertical line.

300

The mathematician, Pythagoras, was from this country.

What is Greece?

300

What instrument did Mr. Ao play in marching band?

The bass drum.

400

What is the formula for the volume of a sphere?

V = (4/3)*pi*r^3

400

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.

400

In what situation would a system of linear equations have infinite solutions?

When the equations both make the same line.

400

If a right triangle has legs of length 5 and length 12, how long is the hypotenuse?

13

400

What sport did Mr. Ao play as a child?

Roller Hockey.

500

What is the formula for scale factor/dilation?

|PQ| = r|P'Q'|

500

What are the three angle pairs we discussed this year?

Corresponding, vertical/opposite, and alternate interior angles.

500

How many solutions does this system of linear equations have?

y = 6x + 14

20 = 2y - 12x

There are no solutions; these are parallel lines.

500

If a right triangle has a leg of length 24 and a hypotenuse of length 25, how long is the missing leg?

7
