distance
what is distance
The distance between two points is the length of the segment between the points
what is a line segments
A line segment is a piece or part of a line having two endpoints. Unlike a line, a line segment has a definite length.
what is a point on a coordinate plane
Each point in the plane is identified by its x-coordinate, or horizontal displacement from the origin, and its y-coordinate, or vertical displacement from the origin
what is a mid point
a point that is in the middle of the line segment joining two points
what is a point
A point is a location. It has neither shape nor
size.named by a capital letter
how to find distance
d=√((x_2-x_1)²+(y_2-y_1)²)
how to find line segments
√((x₂ – x₁)² + (y₂ – y₁)²).
how to locate a point on a coordinate plane
read the number on the x-axis directly above or below the point (x,y)
how to find the midpoint
Add the 2 X-values, then divide by 2. Add the 2 Y-values, then divide by 2.
what is a line
made up of points,one line through 2 points named by 2 letters
what point is 6 away on the x axis from (1,3)
(7,3)
find the measure of DF if DE is 2 7/10 and EF is 5 9/10
8 3/5
locate (3,4)
start at the origin(0,0) and go over 3 to the right and up 4
how to find a bisector
find their midpoint and negative reciprocal, and plug these answers into the equation for a line in slope-intercept form. (slope intercept y = mx + b)
what is a plane
A plane is a flat surface made up of points that
extends infinitely in all directions. There is
exactly one plane through any three points not
on the same line. named by the 3 point
what point is 3 away on the y axis from (4,6)
(4,9)
find the meausre of QR if PQR is 13 3/4 and PQ is 6 5/8
7 1/8
locate (−2,−5)
start at the origin(0,0) and go over 2 to the left and down 5
what is a bisector
a line that divides a line segment or an angle into two equivalent parts. The bisector of a segment always contains the midpoint of the segment.
what is the set of points they have in common
the intersection of two or more geometric figures
what point is 1 above (1,4)
(1,5)
6.5
locate (0,−3)
start at the origin(0,0) the x coordinate is 0, so you don’t move horizontally and go down 3
find the mid point of a(-2,1) and b(8,3)
(3,2)
what is a plane with a b and c
plane ABC
