## Abstract

The invention is a tool for measuring the distance and angle between two points on two surfaces to measure position of the points and surfaces relative to one another to provide the user with angle and distance measurements which fully define the relationship between the surfaces and points without additional calculations.

## Claims

### Claim 1

A tool for measuring angles and lengths between surfaces, the tool comprising:
a longitudinal member having a first end, an extendable second end, and a linear scale;
an angle measuring element connected to the first end of said longitudinal member and configured to measure the angle between the axis of the longitudinal member and a first measurement surface;
a second angle measuring element connected to the extendable second end of the longitudinal member and configured to measure the angle between the axis of the longitudinal member and a second measurement surface; and
wherein the linear scale of the longitudinal member gives the linear distance between the two measurement surfaces.
