Product Description
This all-purpose triangular ruler is designed for easy measurement of angles, slopes, and gradients. It utilizes the Angle Triangle Theorem to accurately determine all angles. The ruler allows you to calculate the slope distance by using the slope horizontal distance (reference plane) and the slope angle. By multiplying the slope scale index with the horizontal distance, you can obtain precise measurements. The ruler can measure slope angles up to 45 degrees by multiplying the slope horizontal distance and the slope angle.
