...obtuse-angled triangle. A EIGHT- ANGLED TRIANGLE has one right angle. Thus, The figure JKL is a right angled **triangle. The side opposite the right angle is called the HYPOTHENUSE, and the** side perpendicular to the base, the PERPENDICULAR. Thus, In the figure JKL, the side JL is the HYPOTHENUSE,... | |
