## Objective:

SOL G.8: The student will solve real-world problems involving right triangles by using properties of special right triangles.

 Applet Directions 1 Close Given: ΔABC is equilateral. Construct a 30-60-90 triangle within the equilateral triangle. Using the perpendicular tool , click on segment BC and then point A. Using the intersection tool , click on the intersection of the perpendicular with segment BC. Consider this as point D. Using the hide tool , click on the perpendicular line. Using the segment tool , create the three sides of ΔABD.

 Applet Directions 2 Close How do the measurements of the sides of ΔABD compare? Using the edit tool , click on each segment to view its length. Drag points A or B to test your hypothesis.
