PRESENTATION OUTLINE
Before you start your journey to save the princess, there's a few things you must know in order to be successful.
A) PREPARING/PRIOR KNOWLEDGE
- Sin= Opposite/hypotenuse and it equals Y. Whereas cos represents X
- An Oblique triangle has no right angles
- The sine function is a/sinA= b/sinB= c/sinC and is used to solve oblique triangles
- Herons formula is used to find the area of a triangle
- How do we use law of sines to solve problems and determine the angle or side of a triangle
B) TRAINING/INTERPRET RULES
Law of sines to solve oblique triangles: If A, B, and C are the measures of the angles of a triangle and a, b, and c are the lengths of the sides then they correspond
Herons area formula is to be used when the lengths of all three sides are given. For example a, b, and c
USING YOUR "S" CALCULATE THE ARE
Now let's test what you've learned. To save the princess!
