A solid wedge indicates this bond or group is projecting out towards the viewer. Some examples of wedges that are used for separating might be a shovel, a knife, an axe, a pick axe, a saw, a needle, scissors, or an ice pick.
But wedges can also hold things together as in the case of a staple, push pins, tack, nail, doorstop, or a shim.
The pattern is characterized by a contracting range in prices coupled with an upward trend in prices known as a rising wedge or a downward trend in prices known as a falling wedge. A wedge pattern is considered to be a pattern which is forming at the top or bottom of the trend. The Falling Wedge is a bullish pattern that begins wide at the top and contracts as prices move lower. This price action forms a cone that slopes down as the reaction highs and reaction lows converge.
The Rising Wedge is a bearish pattern that begins wide at the bottom and contracts as prices move higher and the trading range narrows. In contrast to symmetrical triangles, which have no definitive slope and no bullish or bearish bias, rising wedges definitely slope up and have a bearish bias. A rising wedge is a technical indicator, suggesting a reversal pattern frequently seen in bear markets.
This pattern shows up in charts when the price moves upward with pivot highs and lows converging toward a single point known as the apex. Bullish or Bearish: A Continuation Wedge consists of two converging trend lines. Helmenstine, Anne Marie, Ph. Coordination Number Definition in Chemistry.

I Accept Show Purposes. The following are examples of each, and how they can be used together. Above are 4-carbon chains with attached OH groups or Cl and Br atoms. Remember that each line represents a bond and that the carbons and hydrogens have been omitted.
When you look at or draw these structures, the straight lines illustrate atoms and bonds that are in the same plane, the plane of the paper in this case, computer screen. Dashed lines show atoms and bonds that go into the page, behind the plane, away from you.
In the above example, the OH group is going into the plane, while at the same time a hydrogen comes out wedged. Wedged lines illustrate bonds and atoms that come out of the page, in front of the plane, toward you.
