Define Collinear points
if lines are congruent they are
equal
midpoint formula is
x1+x2/2 and y1+y2/2
an angle is formed by two what with a common endpoint
rays
what is an adjacent angle
two angles that are next to each other
Use the diagram to name three coplanar points
V, Y, X, W
segment addition postulate is
if AB and C are colinear and B is in the middile segment AB plus BC is AC
distance formula is
square root x2-x1 squared plus y2-y1 squared
an angle bisector is a line that divides the angle into
two equal portions
vertical angles are
on the opposite side and identical
Use the diagram to give another name for the plane Q.
Plane IFG, IFE, or IGE
if line cd has a mispoint at b and cd is 50 ab=4x+5
bd is 5x-3
what is the length of ab
line kl has a midpoint J at (3,4) and L is at (7,8)
(-1,0)
two rays xy and by intersect and have an angle measure of 3x+4 a ray cy bisects this angle and makes a section 5x-40 what is the measure of the angle xyb
angle bcd is bisected into sections of 2x and 3x-4 what is x
x=4
Use the diagram to name the intersection of plane K and line c.
line AB has a point in not the exact middle C AC is 5x+3 CB is 2x AB is 3x+11 what is x and the length of line AB
192 and x=27
distance formula is derived from
the pythagerous therom
an angle made by rays xy and dy is made and has a total measure of 43 another ray uy cuts it into two sections the first of which is 3x-4 and the other is 4x+7 what is x
11.5
slide show what is x you have 2 minutes no calc
11.6
Use the diagram to determine how many planes appear in the figure and name four collinear points.
5 planes, Points D, A, B, E
A segment ABCD is split into thirds AB is 4x+5 BC is x+26 CD is unkown what is its length and the length of AD you have 2 minutes
33 and 99
line jx is bisected by line ky at point y. Point j is at (0,0). Point x is at (6,8) point k is 5 units to the right of y and 12 units up. Find the distance between point j and the midpoint of line ky
11.4
tell me the defention of complementary, supplementary, acute obtuse, and right angles you have 90 seconds
comp= adds to 90
supp=adds to 180
ac is less than 90 obt is more and right is 90
refrence slide and find the toal angle
27
