Angles:

• Sum of the interior angles: 180(n-2)

• The exterior angles in a polygon add up to 360 degrees 

Corresponding angles  

Alternate angles  

Interior angles 

Trigonometry for Right-angled Triangles:  

SOH CAH TOA

SOH stands for sine=opposite/hypotenuse

CAH stands for cosine=adjacent/hypotenuse

TOA stands for tangent=opposite/adjacent

1. Label Sides

   1. Side opposite to unknown angle should be labeled as opposite 

   2. The side next to unidentified angle should be labeled as adjacent

   3. Longest side of triangle should be labeled as hypotenuse

Sine, cosine, tangent - Side lengths of a triangle

Sine-1, cosine-1, tangent-1 - Angles of a triangle
