In a right triangle, the length of the side
opposite an angle of 30º is equal to half the
length of the hypotenuse.
6
Using Metric Relations to determine the
length of a segment

• The length of a leg of a right triangle is the
geometric mean between the length of its
projection on the hypotenuse and the
length of the hypotenuse.
• The length of the altitude to the
hypotenuse of a right triangle is the
geometric mean between the lengths of the
segments of the hypotenuse.
• The product of the lengths of the legs of a right
triangle is equal to the hypotenuse
