<h2>Instructions</h2>
|
||
<ul>
|
||
<li>Look at the triangle and decide whether you need to find another angle using 180°, or use the sine rule, or use the cosine rule. Click your choice.</li>
|
||
<li>The formula you chose appears, now click on the variable you want to find.</li>
|
||
<li> The calculation is done for you.<br />
|
||
</li>
|
||
<li> Click again for other rules until you have solved the triangle.</li>
|
||
</ul>
|
||
<p>Note: answers are rounded to 1 decimal place.</p>
