Induced Drag is
- never equal to profile drag.
- equal to profile drag at Vmd.
- equal to profile drag at stalling angle.
Explanation from PART66Online
Induced drag falls with speed while profile (parasite) drag rises with speed; the total drag curve reaches its minimum where the two are equal. That speed is the minimum-drag speed Vmd, so by definition induced drag equals profile drag at Vmd.

Vmd is the speed where the rate of sink is the lowest.
