Measuring and marking the corner of a room to create a triangle to work out angles If you are a dab hand with the old maths then it should be easy enough to calculate the internal angles of a triangle that you can create from eth area you are working in.įor example, you can measure equally each side of a triangle and then also the longer hypotenuse line that joins the 2 other lines together and then from that, work out all the internal angles. There are several ways and tools that you can use to do this: Use Good Old Mathematics With this in mind, it’s essential to firstly work out the exact angle you’re working with. We get hundreds of questions from people about how they can fill big gaps between skirting boards caused because the walls of the room are not exactly at right angles. For example, if you are mitreing two pieces of skirting board together in the corner of a room, chances are that the corner you working in will not be at a perfect 90° In almost all situations, the surface you are working with will not be square, although it may appear to be.

How to Find a Cutting Angleīefore we can actually cut anything, the first job is work out the exact angle that you need to cut to. Some of the most common DIY jobs that involve cutting angles are:Īs you can see from the above, pretty much every area of construction and DIY involves calculating an angle of some sort and ultimately, the overall quality of the finish will depend on how accurate the angles are cut, so it’s imperative that you know how to both work out an angle and then how to cut it. This essentially involves cutting the two joining items at 45° at each end where they meet so that they form a 90° corner. If you have done any DIY in the past, chances are that you have needed to either cut a piece of skirting board or coving at a set angle to form a mitre joint.
Calculating angles and cutting items such as timber, bricks, blocks, boards etc to fit at an angle is an extremely common job in the building trade.
