Copy the triangles below.

1. Label the missing sides with their exact lengths. That is, leave your answers in radical form.

   Hint (a):

   Refer to the Math Notes box for this lesson.

2. The $30° − 60° − 90°$ triangle is sometimes called a half-equilateral. Draw a picture to illustrate this, and explain how that fact can be used to help label the missing sides in part (a).

   Hint (b):

   Reflect the $30°-60°-90°$ triangle across the long leg. This will help you find the hypotenuse.
   Use the Pythagorean Theorem to find the length of the long leg.
