When designing a truss, a truss builder might know the base angle measurement and the lengur UI te te verleeu. 11
compute the height of the king post. Let's take a look at some right triangles to see whether knowing the measure of an acute angle of a right
triangle and the length of one of the sides is enough to find the lengths of the other two sides.
You will use GeoGebra to explore the trigonometric ratios when an acute angle is fixed for a given right triangle. Go to trigonometric ratios
and complete each step below. The right triangle represents half of a king post truss. If you need help, follow these instructions for using
