WebIn the Napier’s circle, the sine of any middle part is equal to the product of the tangents of its adjacent parts. Spherical triangle can have one or two or three 90° interior angle. Spherical triangle is said to be right if only one of its included angle is equal to 90°. Triangles with more than one 90° angle are oblique. WebIn any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two …
WebIncluded angles can be used to determine the area of a triangle as long as the sides that include the angle are known. The equation to find the area is: Area = ( ab sin C) / 2. Now let's find the ... WebAll right triangles have two legs, which may or may not be congruent. The legs of a right triangle meet at a right angle.
