Review HW #4: and Special Triangles

TRIGONOMETRIC RATIOS: OPPOSITE SIDE: Given an angle of a triangle, the opposite side is the side opposite of that angle. ADJACENT SIDE: Given an angle of a triangle, the adjacent side is next to/beside that angle. HYPOTENUSE: The hypotenuse is the side of the triangle that connect the two legs of the triangle.

TRIGONOMETRIC RATIOS:
