there is a shape of right -angled triangle with the two shorter sides of 9m and 5m in a garden .the area of a pond in the middle of the garden is 12.8 square m ,what is the remaining area of the garden for planting grass?
The Pythagorean theorem gives a fundamental relationship between the lengths of the three sides of a right-angled triangle. We make the case for which theorems of elementary Euclidean geometry should be called the "Pythagorean theorem for an arbitrary triangle" and the "Pythagorean theorem for a ...
