# Right Triangle Trig Intro and Exploration

## Students: Choose a random angle measure between 15° and 40°. Set the value of α equal to this value you and your group members chose.

In the input box on the left, type "" (without the " "). Compare this ratio value with the value the rest of the students in your group got. What do you notice?

Now move points A and B around. Pay attention to the decimal value of . Compare the value of this ratio with the ratio values other members in your group have. What do you notice?

Why on earth do you and your group members notice the phenomena you do? Hint: What is so special about all the triangles you and your group members have constructed? Explain!
