Question

Identify the term that completes the equation. AC^2 = (DC)(?)

BC
AD
BD
AB

Answer 1

BC

Explanation:

the height of a right-angled triangle to the Hypotenuse is the square root of the product of the lengths of the 2 segments of the Hypotenuse.

so the square of the height is then the product of the 2 line segments of the Hypotenuse.

therefore

AC² = DC × BC
