A triangular shaped face is more so like a heart shaped face and has a wider forehead which keeps narrowing as it moves towards the chin, which is generally pointed.
1) Bangs with a zigzag parting look good on a triangular face as the sides fall softly while the jaw line is kept uncovered. The bags should be worn over any one side and should be sweeping diagonally so as to become the eye-catching feature of the hairstyle. This will create a magical effect and will drive away attention from the wider forehead area.
2) If you have slightly wavy hair or even possess naturally curly hair, you can go for soft layers throughout and opt for a center parting. This will help divide the top of the face into two parts while imparting an illusion of more length. These soft layers even look good with straight hair and work well with medium hair lengths.
3) You can try out this great combination of long as well as medium layers in this hairstyle which imparts a rounding effect. Soft bangs are optional though they help in framing the face around the forehead and the temples.
4) If you are in favor of a retro look, try the backwards graduation or waves which have a backward slant. It will keep away extra strands of your away from the chin area but would give a look which diverts attention from the broader forehead.
5) A medium parting with straight sleek cut not highlights the eye area it also helps to soften the prominent jaw line of a triangular face. If you like to keep your straight medium hair length looking sleek and neat, this hairstyle is a great option to sport. You can wear the hair partly tied or even let your medium hair down for all occasions. This style works best with straight hair though.
