Erika's Theorems..

Sum of < of triangles
-Sum of interior angles add up to 180.







Complementary: -Add up to 90.









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










Vertically Opposite Angles:
-Angles opposite from each other are corresponding.
<1 and <3
<4 and <2
