the distance formula to find the length of the sides... opposite sides equal it could be a rectangle or parallelogram all sides equal, square or rhombus adjacent equal, kite and then the slope is used to check angles if the product of the 2 lines in -1 the lines are perpendicular (right angle) the the slopes of 2 lines are the same the sides are parallel.
I think this is it ^_^
2*27= 54 which is an even number, not a perfect square, odd or prime. The prime factorization would be 2*3^3
B, Even
Say, for example, you have an improper fraction (it usually is if you're trying to convert to a mixed number) like: 55/7
You would take the highest number that is divisible by the denominator, which in this case is 7 (7x7=49; 7x8 would be 56 and we don't want that)
You subtract the number you got (49) from the original numerator (55).
That will give you 6.
Now, you put the whole number (7) before the fraction (6/7)
Step-by-step explanation:
1=109°
2=3=(360-2*109)/2=142/2=71
