Points, Lines, Planes
Name a segment
PT, TN, PN, QT, QR, or MT
I is the midpoint of WN
WI = 15x - 13
IN = 17
Find x
x = 2
OR is the angle bisector of COY
mCOR = 25
mROY = 3x + 1
Find mROY
mROY = 25
Angles M and Q are what?
(corresponding, alt ext, alt int, same-side int)
Alternate Interior Angles
Is angle t congruent to angle h or angle f?
Angle f.
t and f are alternate exterior angles, so they are congruent.
Another name for line TN
line g, PN, or PT
WI = IN
WI = 36
IN = 5x + 1
Find x
x = 7
angle COR = angle ROY
mCOR = 64
mROY = 9x-8
Find x
Angles O and Q are what?
(corresponding, alt ext, alt int, same-side int)
Same-Side Interior Angles
Is angle c congruent to h or g?
Angle g.
g and c are alternate interior angles, so they are congruent.
Name a pair of opposite rays
TP and TN
or
TR and TQ
I is the midpoint of WN
WI = 15x - 13
IN = 8x - 6
Find x
x = 1
OR is the angle bisector of COY
mCOR = 3x + 2
mROY = 4x - 8
Find x
x = 10
Angles X and Z are what?
(corresponding, alt ext, alt int, same-side int)
Corresponding Angles
When you add angles g and a together, what number do you get?
180
g and a are supplementary angles.
Name three collinear points
P, T, N
or
R, T, Q
WI = IN
WI = -3x + 25
IN = 5x + 1
Find IN
IN = 16
angle ROC = angle YOR
mROC =5x - 1
mYOR = 3x + 7
Find mYOR
mYOR = 19
True or False:
"Two skew lines are coplanar."
False. Skew lines are neither coplanar nor parallel, and they don't intersect.
If the measure of angle t = 110
What does angle c =?
110
Name three coplanar points
Any combination of:
P, T, Q, R, N

WI = 93
OR is the angle bisector of COY
mROY = 3x + 15
mCOR = 7x - 13
Find mROY
mROY = 36
True or False:
"Corresponding angles are on the same side of the transversal."
True
What does angle a =?
95
