Why is the pituitary gland called the master gland? It is the largest gland in the body,
It regulates the work of many glands in the body,
It helps the brain master higher level thinking processes,
It controls the heart, which is the master pumping organ in the body,

The pituitary gland is sometimes called the "master" gland of the endocrine system because it controls the functions of many of the other endocrine glands.

Hope this helps you

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
