define the word midpoint
the midpoint of a segment is the point that divides the segment into two congruent segments
which type of angle has a measure between 90 degrees and 180 degrees
obtuse angles
if two angles are complementary angles what degree measures do they add up to
90 degrees
what is the difference between a line segment
a line has two arrows and line segment has two endpoints
find the midpoint of (-4,0) (-4,4)
(0,0)
what's another way to write
AB
BA
what is the name of the shared endpoint that connects two rays to create an angle
vertex
adjacent angles are two angles that share a common vertex a common side but do not overlap
define the word angle bisector
an angle bisector is a ray that divides an angle into two angles that are congruent
find the midpoint of (5,7) and (-3,4)
(1,5.5)
Distance on a Number Line
The distance between two points is the length of the
segment between the points. The coordinates of the
points can be used to find the length of the segment
define the word segment bisector
a segment bisector is a point,ray,line,or line segment that intersects the segment at its midpoint.
A point is a location. It has neither shape nor
size.
A .
why do we use distance formula
to find the distance between two points
find the distance between (-4,0) (-4,4)
8
what is distance formula?
d=√((x_2-x_1)²+(y_2-y_1)²)
what is a graph used for
to show where points are located
(7,3) and (2,5)
5.39
what is the between (,11) and (8,4)
7
find the distance between (5,7) and (-3,4)
8.54
two angles form a linear pair the measure of one angles is nine times the measure of the other angles find the measure of each angle
angle 1=18 degrees
Angle 2=162 degrees
what other formula is the distance formula a part of
the Pythagorean theorem
write an equation for the perpendicular biscetor of the line segment joining A(-1,4) and B(5,2)
y=3x-3
use the distance formula to find the length of segment AB with endpoints A (-5,4) and B (7,9)
distance =13
use the midpoint formula to find the midpoint between points A(6,-4) and B(4,2)
midpoint(5,-1)
