= 19.27 in2
100
Find the area of the following.
(6 + 13) * 4 = 38 in2
100
Find the area of the following polygon.
234 + 104 = 338 in2
100
What are the names of the following figures?
sphere, pyramid, rectangular prism
cylinder, cube, cone

What does perimeter mean? What is the perimeter of a square that has a side of 17 in?
perimeter = adding all the sides of a polygon
17 + 17 + 17 + 17 = 68 in
200
True or False:
The formula for the area of a triangle is 1/2 * b * h.
True!
1/2 * b * h is the same thing as (b * h) / 2
200
Find the area of a trapezoid that has a base of 17 m, another base of 21 m, and a height of 12 m.
a = [(b1 + b2) * h ] / 2
17 + 21 = 38 * 12 = 456 / 2 = 228 m2

What are the names of these three angles?
a.) <
b.) \_
c.) l_
a.) acute
b.) obtuse
c.) right
200
What is the median of the following numbers?
18, 12, 14, 15, 19, 14, 12, 25
Order them: 12, 12, 14, 14, 15, 18, 19, 25
The middle two numbers are 14 and 15.
Add them up and divide by 2 = 29/2 = 14.5
300
Find the area of the parallelogram.
8 * 15 = 120 in2
300
[(11 + 19) * 15] / 2= 225 cm2
300
Find the area of the following.
112 + 24 = 136 cm2
300
A school desk has a length of 3 feet, a width of 2.5 feet, and a depth (height) of 1.75 feet. What is the volume of the desk?
v = 3 * 2.5 * 1.75
v = 13.125 ft3
300
When dealing with circles in geometry, there's a fancy number with an edible name that is used. What is it called? How do we write it?
Pi!
400
Find the missing BASE.
b = 10 km

A Palestinian poet named Refaat Alareer wrote a beautiful poem about a kite titled "If I Must Die" before before he was killed (it's great, you should read it). Sr. Bissan decided to make a kite in his honor. What is the area of the kite she made?
a = (a)triangle 1 + (a)triangle 2
a = 48 + 84 = 132 square units
400
Find the area of the following.
= 57.5 units2
400
A cube has a side of 2/3 m. What is its volume?
since a cube's sides are all the same, the volume would be 2/3 * 2/3 * 2/3 = 8/27 m3
400
What are parallel and perpendicular lines? Draw them!
parallel - two straight lines that never meet || or =
perpendicular - two lines that intersect (cross) each other at a right angle (90 degrees)
500
A piece of square toast is cut diagonally into two right triangle slices. If the side of the toast was 16 cm, what is the area of one of the triangular slices?
16 * 16 = 256 / 2 =
= 128 cm2
500
10.5 + 21 = 31.5 ft2
500
Find the area of the following. (hint: try subtracting!)
Find the area of the WHOLE trapezoid.
[(3.5 + 6.5) * 4] / 2 = 20
Find the area of the missing triangle.
(3 * 4) / 2 = 6
20 - 6 = 14 cm2
500
Using what you know about volume of a prism (and also, logic), find the volume of a TRIANGULAR prism.
Area of Triangle * the third side!
28 * 12 = 336 m3

Complementary angles are angles that add up to 90 degrees.
Supplementary angles are angles that add up to 180 degrees.
Which type of angles are always acute?
Complementary angles!
