The function iterools.combinations () is handy for this purpose: min_distance = distance (fList [0], fList [1]) for p0, p1 in itertools.combinations (fList, 2): min_distance = min (min_distance, distance (p0, p1)) An alternative is to define distance () to accept the pair of . Then △PQR\triangle PQR△PQR is a right angled triangle, and we can apply the Pythagorean theorem to obtain. Points Lines and Line Segments. Solution: In Example 2, the difference between 9 and -1 is . Find a point on the yyy-axis which is equidistant from the points A=(−3,4)A=(-3,4)A=(−3,4) and B=(7,6)B=(7,6)B=(7,6). Use the formula from above. Midpoint. Now that we know the slope of the line that will give the shortest distance from the point to the given line, we can plug the coordinates of our point into the formula for a line to get the full equation of the new line: The number line is the main visual base in statistics and we often want to look at two points on the number line and determine the distance between them. Once you've done that, just add the numbers that are under the radical sign and solve for d. d=∣2⋅1−1⋅7+2016∣22+(−1)2=20115. Moreover, since AB2+BC2=52+52=50=CA2,{AB}^2 + {BC}^2 = 5^2 + 5^2= 50 = {CA}^2,AB2+BC2=52+52=50=CA2, it is right-angled. \end{aligned}(Area of ABCD)=AB×BC=62×32=36.
