Question

.Pythagoras theorem helps calculate the size of a:

Answer 1

PGT MEANS
H²=B²+P²
where h is hypotnus b is base and p is perpendicular ...u can use this to calculate any side of the triangle .

Answer 2

The Pythagorean theorem states that the square of the hypotenuse that is the side opposite to the right angle is equal to the sum of the squares of the other two sides.

It is used when the length of two sides of a right triangle are known and the length of the third side has to be found. It is also used for computing the distance between points on a plane, computing perimeters, volumes and surface areas of various geometric shapes, and converting between polar and rectangular coordinates.
