An equilateral triangle is a triangle with all three sides equal (Figure 1,a). In an isosceles triangle only two of the sides are equal (Figure 1,b). A triangle whose interior angles are all acute is called an acute triangle (Figure 1,c). If one of the angles is a right angle, ...
degree angle; two sides to form a 142.5 degree angle with the hypotenuse, and the short side at right angles to form a 82.5 degree angle and 97.5 degrees clip angle; three sides to form a 90 degree angle with the short right-angle side, and the side two to form a 7.5-degree angle....
A 30-60-90 triangle is a special right triangle (a right triangle being any triangle that contains a 90 degree angle) that always has degree angles of 30 degrees, 60 degrees, and 90 degrees. Because it is a special triangle, it also has side length values which are always in a consist...
