Right Angled Triangle
- Requires an angle of 90
degrees
- Remember: the sum of the
angles of all triangles in 2D will always be 180 degrees
SLIDE 3
Sine Function
- Sine function (sin),
defined as the ratio of the side opposite the angle to the hypotenuse.
SLIDE 4
Cosine Function
- Cosine function
(cos), defined as the ratio of the adjacent leg to the hypotenuse.
SLIDE 5
Tangent Function
- Tangent function
(tan), defined as the ratio of the opposite leg to the adjacent leg.
SLIDE 6
Remember
- The hypotenuse is the side opposite to the 90 degree
angle in a right triangle; it is the longest side of the triangle and one of the two sides adjacent to angle A.
- The adjacent leg is the other side that is adjacent to
angle A.
- The opposite side is the side that is opposite to angle A.
