You should be able to
know how to identify the different sides of a right-angled triangle with any given angle in the triangle
know the trigonometric ratio for sine, cosine and tangent
Success Criteria:
I am able to
identify all the different sides of a right-angled triangle with any given angles
formulate the formula for sine, cosine and tangent
Always look through all examples in textbook before lesson.
Note:
Three conditions to check before applying the trigonometric ratios.
Is the triangle a right-angled triangle
what is the given angle
identify the 3 sides based on the given angle
