38, 64, 75

41, 56, 83

25, 89, 40

The sum of the two non-adjacent interior angles of a triangle are the same measure as the exterior angle. The adjacent interior angle of a triangle and the exterior angle add up to

180\degree

Examples on whiteboard

Part Two

Parallel Lines with Transversals

Transversals are lines that cut through parallel lines

Congruent means same, supplementary means add up to $180\degree$
Corresponding: In the same corner (congruent)
Vertical: Across (congruent)
Same-Side Interior - supplementary
Same-Side Exterior - supplementary
Alternate Interior - congruent
Alternate Exterior - congruent

Multiple Choice

Alternate Interior

Alternate Exterior

Corresponding

Same-Side Interior

Multiple Choice

What is the relationship of the angles

Alternate Interior

Alternate Exterior

Corresponding

Vertical

Multiple Choice

50^o

90^o

130^o

360^o

Part Three

Pythagorean Theorem

a²+ b²= c²

"Diagonal" refers to the hypotenuse (c)
