What is...Exterior Angle Thereom
400
Are these 2 triangles similar?

a= 70
b= 45
c= 65
d= 45
e= 70
f= 110
500
Two intersecting lines that create four 90 degree angles
What is Perpendicular Lines
500
At least 2 angles in a pair of triangles must be congruent to prove similarity
What is....Angle Angle Criterion for Similarity
500
Solve for X
what is...x = 4.5
500
Find x,y, and z.
What is...
x = 52
y = 134
z = 82
500
What is...yes they are. because Angle Angle criterion says we only need to know 2 angles to prove similarity. They have Angle B in common. And angle A and D are CORRESPONDING angles, so they must be congruent. (or angles C and E).
