Answer:
equilateral triangle
Step-by-step explanation:
EQUILATERAL ... all three sides are equal length
ISOSCELES ... two sides are equal length
SCALENE ... none of the three sides are equal length
RIGHT ... one of the angles measures 90 degrees
OBTUSE ... one of the angles measures greater than 90 degrees
ACUTE ... all three angles measure less than 90 degrees

Step-by-step explanation:
Given

Which would not prove the similarity
implies that:
The following angles are congruent
And the following lengths are congruent
The options are not clear; so, it's a bit difficult to select the correct option.
<em>Any of the options that is different from the above list of 6 congruent pairs is the answer to your question.</em>
Since the 8 in the first number is in the thousands place, its value it 8*1000=8000.
Since the 8 in the second number is in the hundreds place, its value is 8*100=800.
8000 is ten times 800.
Final answer: 10x as large
Given:
r = radius = 4
h = height = 12
dr = error in radius = 0.2
What we want to find
dV = error in volume
Use the derivative to find the differential dV
V = pi*r^2*h
dV/dr = d/dr[ pi*r^2*h ]
dV/dr = 2pi*r*h
dV = 2pi*r*h*dr
dV = 2pi*4*12*0.2
dV = 19.2pi
So if the error in measuring the radius is +-0.2 inches, then the error in the cylinder volume is +-19.2pi cubic inches (we either measure the volume to be 19.2pi cubic inches too big, or 19.2pi cubic inches too small)
----------------------------------------------------------------------------------
Final Answer: Plus or minus 19.2pi cubic inches
Note: your teacher may want you to drop the "plus or minus" part
