<p>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.</p> <p>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.</p>

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

<p>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.</p>

<p>This PowerPoint contains solutions to the corresponding Worksheet and walks through the solutions set by set with the students when displayed on the whiteboard.</p> <p>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.</p>

<p>This is a two page resource.<br /> 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.<br /> It incorporates two examples and two Check for Understanding questions on finding the missing length in a right-angled triangle.</p>
