### Erika's Theorems..

Sum of < of triangles

-Sum of interior angles add up to 180.

30, 60, 90 triangle

-The opposite side of 30 is half of the hypotenuse.

mAB= mAC

2

Alternate Exterior Angles:

-Congruent

<1 is congruent <4

<2 is congruent <3

Alternate Interior Angles:

-Congruent

<3 is congruent <6

<4 is congruent <5

Co-Interior Angles:

-Supplementary

<1 + <6= 180

<4 + <7 = 180

**Corresponding Angles:**

-Have the same Angles

<4 and <2
