Given any kind of triangle, you can find its side lengths by applying the Pythagorean Theorem for right triangles, depending on what information you’re given. You will use GeoGebra to see how the Pythagorean Theorem can be used to solve non-right triangles. Go to right triangles and the Pythagorean Theorem, and complete each step below. If you need help, follow these instructions for using GeoGebra. Question 1
Create a line through point B perpendicular to and label the intersection of the perpendicular line and point D. Measure and record BD and m∠BDA. What do you know about ∆ABD and ∆BCD based on their angle measurements? (If you accidentally move point B before taking your measurements, use the “Move B back to initial position” button.)
