Right Triangle Trig Intro and Exploration

Student groups: Choose a random angle measure between 15° and 40°. Be sure each group member sets the value of the acute angle equal to this value you and your group members chose.

In the input box on the left, type "[math]\frac{\text{opp}}{\text{hyp}}[/math]" (without the " "). What is the value of this ratio (approximately)?

Now move the vertices (corners) of this triangle around. Pay attention to the decimal value of [math]\frac{\text{opp}}{\text{hyp}}[/math] as you do. Compare the value of your ratio with the ratio values other members in your group got. [br][br]What do you notice?

Student groups: Use the same angle measure you chose in the first app above. Set the value of this angle (below) equal to that value. Then answer the questions that follow.
