Thats just a general statement. All the vipers will have the triangular head, but the cobras, as well as others don't have the triangle.Hope this helps a little.

Please don't rely on the shape of a snakes head as a sole means of identification, as stated by SShane that is a rather "general" description a prime example in North America is the Coral snake which has a rather blunt shaped head, But the Coral is a truly venomous snake,
Hope that this is usefull.

Another reason relying on head shape can lead to mis-identification is that several NA non-venomous snakes, in defensive posture, have a head that seems rather distinct from the neck. Among them are the genera Nerodia & Thamnophis. I realize Thamnophis are heading toward being opisthoglyphs & can cause some discomfort in some cases, but they are not dangerously venomous.
Check out the cottonmouth page on the site below for a pic of a cottonmuth & watersnake side-by-side, & you'll see what I mean about not wanting to rely on head shape.
