hypothenuse การใช้

The posterior dorsal surface of the first dorsal fin is covered with a belt of up to nine rows of enlarged dermal denticles . is roughly a right triangle in shape, with the hypothenuse concave anterodorsally.
Then you have a right angled triangle with the radius of the sphere, 1, as the hypothenuse and " d " and " r " the radius of the circle as the other two sides.
The geometric mean theorem can also be thought of a special case of the intersecting chords theorem for a circle, since converse of Thales'theorem ensures that the hypothenuse of the right angled triangle is the diameter of its circumcircle.
*Problem 20 : " Suppose the long side of a right angle triangle equals to sixteen and a half, the square of the product of the short side and the hypothenuse equals to one hundred sixty four and 14 parts of 25, question, what is the length of the short side ?"
If we consider a cell of the " net ", we can see that the cell is a rhombus : it is a parallelogram with the four sides equal to d = \ frac { p } { \ sin \ alpha }; ( we have a right triangle which hypothenuse is d and the side opposed to the \ alpha angle is p ).
