This worksheet incorporates using the knowledge of SOH, CAH, TOA to label the sides of a right-angled triangle before advancing to applying this knowledge to other right-angled triangles to find the exact trig values and entering them into a table. It is a nice activity for students to learn where the exact trig values come from and having a nice compact table of the values for students to use in future lessons where exact trig values are used often.

This is a one page resource containing 4 challenge questions on finding the missing length in a right-angled triangle for students to either work on or be displayed on an interactive whiteboard.

This PowerPoint contains solutions to the corresponding Worksheet and walks through the solutions set by set with the students when displayed on the whiteboard. The final slide presents extension questions to move onto once the activity is completed or can be used as a print out for students who work faster than others in the classroom.

This worksheet incorporates questions applying the exact trig values to right-angled triangles to find the missing length.

This is a two page resource. The first slide is a table of the exact trig values to display on the whiteboard while the second is a print out for the students to work on. It incorporates two examples and two Check for Understanding questions on finding the missing length in a right-angled triangle.
