1. A protractor for assistance in determining miter saw angle settings for miter cuts, said protractor comprising:
- a top edge;
at least one face with angle markings;
a bottom edge; and
a tab adjacent to the bottom edge and extending lower than said bottom edge, wherein the at least one face further comprises a horizontal line, disposed near or on the bottom edge and parallel to the bottom edge, at least one vertical axis, disposed perpendicularly on the horizontal line, at least one origin defined as a point where the horizontal line intersects with the at least one vertical axis, at least one raised member having at least one raised edge, and the at least one raised edge is perpendicular to the at least one face and intersects said at least one face at a point which is the at least one origin.

Abstract
An angle indicating instrument which, used in conjunction with a sliding T-Bevel, can indicate to users what miter saw setting to use when cutting two pieces of material for a miter joint, or for cutting one piece of material requiring a miter cut.

5. A method for using a protractor for determining miter saw angle settings for miter cuts, the protractor comprising:
-
a top edge; at least one face with angle markings; a bottom edge; and a tab adjacent to the bottom edge and extending lower than said bottom edge, wherein the at least one face further comprises a horizontal line, disposed near or on the bottom edge and parallel to the bottom edge, at least one vertical axis, disposed perpendicularly on the horizontal line, at least one origin defined as a point where the horizontal line intersects with the at least one vertical axis, at least one raised member having at least one raised edge, and the at least one raised edge is perpendicular to the at least one face and intersects said at least one face at a point which is the at least one origin, said method comprising the steps of; Transferring a target angle to a Sliding T-Bevel having a handle edge and a blade edge; Positioning said Sliding T-Bevel in a functional engagement with said protractor, wherein the handle edge is in abutting engagement with the bottom edge and the blade edge is aligned with the at least one origin; Reading a resultant miter saw angle setting value according to a nearest alignment between the blade edge and the angle markings, wherein said tab prevents the handle of the Sliding T-Bevel from engaging the bottom edge of the protractor in an improper orientation. - View Dependent Claims (6)

7. A kit comprising:
-
a protractor comprising; a top edge; at least one face with angle markings; a bottom edge; and a tab adjacent to the bottom edge and extending lower than said bottom edge, wherein the at least one face further comprises a horizontal line, disposed near or on the bottom edge and parallel to the bottom edge, at least one vertical axis, disposed perpendicularly on the horizontal line, at least one origin defined as a point where the horizontal line intersects with the at least one vertical axis, at least one raised member having at least one raised edge, and the at least one raised edge is perpendicular to the at least one face and intersects said at least one face at a point which is the at least one origin; and a customized Sliding T-Bevel having a handle edge and a blade, wherein said protractor is further fitted with protractor centering means;
said customized Sliding T-Bevel is further fitted with T-bevel centering means;
said protractor centering means are adapted to effect a reversible interlocking engagement with said bevel centering means;
whereby said interlocking engagement automatically aligns the blade with the at least one origin; and
wherein said protractor centering means and T-bevel centering means are selected from the group consisting of pin and hole;
matching interlocking members;
magnetic centering means;
key and hole centering means;
hook and loop centering means;
socket and ball centering means; and
snap centering means. - View Dependent Claims (8)
