Solve for X

X = 9
Which theorem could be used to prove the lines are parallel?

Find the value of each variable.

What is x=67, y=113, z=50 ?
He is the Patron Saint of animals.
What is Saint Francis of Assisi

Which segments are skew to AB?

FG, EH, DH, CG
Which solution for the value of x is incorrect and WHY?

Answer B is incorrect because alternate interior angles are congrurent to each other, not supplementary.
Fix the error: If two alternate exterior angles are supplementary, then the two lines being cut by the transversal are parallel.
What is congruent?
The name for angle 4 based on where it is in the triangle.

Exterior angle
This geometric shape is often used to represent the Holy Trinity.

Why are <2 and <7 not alternate exterior angles?

They are on the same side of the transversal.
Given: m<2 = 113
Find: m<1=__ m<2=__ m<3=__ m<4=__ m<5=__ m<6=__ m<7=__ m<8=__

m<1=67 m<2=113 m<3=67 m<4=113 m<5=67 m<6=113 m<7=67 m<8=113
