Coplanar/Collinear
Points A,B, and C lie on a straight Point. Point D does not,which points are Col-linear
Points A,B and C are Col-linear.
the exact middle of a line segment.
what is distance Formula?
D is the square root of (x2-x1)2 +(y2-y1)2
what is section Formula?
a tool to find the coordinates of a point that divides a line segment into two parts with a ratio.
what is fractional distance formula?
it finds a specific point along a directed line segment by moving a fractional part of the way from start to finish.
Are two random points in space always Co-linear? if so explain why.
Yes,you can always have them as Co-Linear by making a single straight line and having both points EX: -AB
solve.
A(2,4) B(6,10)
M=4,7
what is the distance of (1,2) and (4,6)?
5 units.
find the coordinates of P which divides into the points (4,-3) and (8,5) when the internally is 3:1
P is equal to 7,3
Find the point that is 1/2 away from A(2,4) and B(10,12)
6,8
Solve. A(-2,1) B(2,3) C(6,5) are the points Co-linear? show your work.
yes. AB and BC both equal 1/2 so both together give a Co-linear answer.
C(-3,5) D(7,-1)
2,2
what is the distance between (-2,3) and (4,-5)
10 units
in what ratio does p(-4,6) divide into the line segment points of A(-6,10) and B(3,-8)?
K equals 2/7
find the 1/3 mark of A(-3,6) and B(6,-4)
0,2
find the missing value,show your work.
P(1,3) Q(4,y) R(10,15)
Y=7.
PR=4/3 and PQ =4/3 so Y=7
E(1,-4) F(4,7)
2.5,1.5
what is the distance of the points (-1.7,9.35) and (7,-3)
rounded to the nearest tenth gives you 15.1 units.
Find point Q which divides into the line of A(2,1) and B(4,3) with externally in the ratio being 4:3
Q is equal to 10,9
find the coordinates of 3/4 from A(1,2) and B(9,14)
7,11
solve,show your work.
A(1,2) B(3,5) C(7,k)
K=11
the midpoint of segment GH is M(3,4) and if the endpoint G is at (1,2) what are the coordinates of endpoint H?
M=5,6
if the distance between the point (X,2) and the point (0,-1) is 5 and X>0,what is the value of X?
X is equal to 4.
Find P which divides into the joining line segment of A(2,-3) and B(7,2) internally in the ratio of 3:2
P is equal to (5,0)
find 2/3 of points A(2,-1) and B(12,14)
