CLAIM :
1. An angle indicating instrument, wherein said instrument is adapted for engagement over a range of angles of from slightly greater than 0° up to 180°, any such angle being referred to as the engaged angle when engaged by said instrument, wherein said engaged angle relates to a piece of material to be cut, and wherein said instrument is used to indicate and specifically refer to a cutting angle of a bevelled cut to be made in said piece of material; said angle indicating instrument comprising:
a first arm;
a second arm;
said first and second arms being joined together in angularly variable relation to one another, with the angle between said first arm and said second arm being said engaged angle; wherein said first arm has an angle indicating means for indicating angles that are the complement of one half of said engaged angle, and that are to be used for forming a bevelled cut to be made in said piece of material to be cut in order to adapt said piece of material for bevelled adjoinment to another piece of material, wherein said angle indicating means comprises at least a first scale, and wherein said first scale is a scale that has angle readings from 0° to 90° that are evenly displaced over an angular range of 180*;
a reference means on said second arm for reading an angle on said angle indicating means that .is the complement of said angle to be cut; and
wherein said reference means refers on said first scale to an angle that is the complement of one half of said engaged angle.

2. The angle indicating instrument of claim 1, wherein said indicating means comprises at least one scale.

3. The angle indicating instrument of claim 2, wherein said indicating means comprises a first scale and a second scale.

4. The angle indicating instrument of claim 2, wherein said scale is an angular analogue scale.

5. The angle indicating instrument of claim 4, wherein said scale indicates the complement of an angle that is one half the angle of said engaged angle.

6. The angle indicating instrument of claim 4, wherein said scale indicates an angle that is complementary to said engaged angle for acute values of said engaged angle, and indicates an angle that is 90* less than said engaged angle for obtuse values of said engaged angle.

7. The angle indicating instrument of claim 1, wherein said angle indicating means comprises a digital readout.

8. The angle indicating instrument of claim 1, wherein said angle indicating means provides an auditory representation of the angle being indicated.
