In a triangular pyramid ABCD AB = 4cm, BC = 2cm, BD = 3cm, AC = 2.5cm. Find the length of vectors AB, BC, BD, AC.

Given:

Triangular pyramid ABCD;
AB = 4 cm;
BC = 2 cm;
BD = 3 cm;
AC = 2.5 cm.
Find: the length of vectors AB, BC, BD, AC.

1) The module of the vector AB is equal to:

Since the side of the base of the triangular pyramid is equal to AB = 4 cm, then the length of the vector AB is also equal to 4 cm.

2) Similarly, BC = 2 cm, BD = 3 cm, AC = 3 cm.
