Complainer/Collinear
What does congruent mean?
Similar/the same, =
what is the definition of midpoint?
the exact middle point of a line segment
Find the distance between L (4,2) and B (1,-5)
sqaured 58 or 7.62 units
what is the section formula?
what is the difference between ratio and fractional distance formula?
one uses a ratio to divide while other uses a fraction
What does Coplaner mean?
Points/lines that are on the exact same surface (plane)
what is mid point formula?
look at 4
Does it matter which is labeled x1,x2,y1,x2, and why or why not?
Yes, this is very important because each point is a different number.
what is the point of m:n?
they are your ratio numbers
what does a/b mean?
it is your fraction used during your formula
Show me a Collinear
look on page 1
what is the correct way to find the midpoint?
find x1 and x2 and subtract then divide by2
What is distance Formula?
/(x2-x1)2+ (y2-y1)2
the coordinates of the midpoint are (2,4) (6,10)
(4,7)
what point must you subtract first from the ending point inside the parentheses
starting point
Show me an example of a plane
look at 2
what is the way to find midpoint within a coordinate plane?
first label all your numbers then find your x value by adding both x's then divide by 2.
To find Y, add Y1 and Y2 then divide by 2
What is the distance Formula on number line?
If point P divides the segment between A (0,0) and B (4,4) in a ratio of 1:1 what is the x value of P
2
what does it mean when points are noncollinear
look at 3
(points are'nt all on same line)
Is it okay to switch which is y1,y2 and x1,x2 while using the midpoint formula?
Yes!!
Exact distance definition?
Length of the segment between two points. Coordinates of points can be used to find length of segment.
If not told if a division is internal or external, what are you to assume it is?
Internal division.
