Jeremiah made his Angle Getter from a protractor, a coat
hanger wire and a carpenter's line level. In the Angle Getter kit, all
these things are included. Plus you get graph paper to figure
out distances when you estimate distances. 

Jeremiah is shown here measuring the angle of a rafter.
It was trying to do this job that led Jeremiah to invent the Angle getter in
the first place. 

Here is another way Jeremiah learned to measure an angle.
He loosened the wire so that it hung free. When it was hanging
straight down, he tightened the wingnut and read the angle. This
technique makes it easy to transfer the correct angle to a rafter waiting to
be cut. 

Here, Jeremiah is drawing a line on a new rafter using the
Angle Getter. 

Jeremiah found out that he could estimate distances using
his Angle Getter. He operated from a base line. (In this case a picket
fence outside his house. ) He measured two angles to the house across the
street, one on each end of the base line. 

Then, using the graph paper, he drew a small triangle like
the big one he actually had made. This is called a scale drawing.
More complete instructions are inside the Angle Getter kit. 

Jeremiah used the same system to find out how far the horse
chestnut tree is from his back yard. There wasn't a fence there so he
tied a string between two stakes to make his base line. 

Jeremiah also found out that he could measure
the height of the flagpole at school. He used the same system, but the
ground became the base line. 

Then using the graph paper, he drew a scale
drawing of the flagpole using the angle he determined by sighting along the
edge of the Angle Getter to the top of the flagpole.
