The tangent ratio Explicit teaching
The tangent ratio part 1 Visible learning Learning intentions To be able to use language associated with trigonometry to describe right-angled triangles. To know and be able to define the tangent ratio. Success criteria I can identify the hypotenuse, opposite and adjacent sides with respect to an angle in a right-angled triangle. I can explain the relationship between the value of tan30?found in my calculator and a right-angled triangle with a 30? angle. I can write the tangent ratio for a given angle in a right-angled triangle.
The tangent ratio part 2 Launch Look at your calculator with a partner. Write down any of the buttons that you aren't sure what they do. Think pair share 3

Success criteria I can identify the hypotenuse, opposite and adjacent sides with respect to a given angle in a right-angled triangle. I can explain the relationship between the value of tan30? found in my calculator and a right-angled triangle with a 30? angle. I can write the tangent ratio for a given angle in a right-angled triangle.
