If you re making a five sided project with all sides equal you divide 360 by five to get 72 degrees.
How to figure an outside gutter angles.
Save money save sealant save time.
Measure from the chalk mark to the opposite corner of the gutter making another chalk mark and moving the ladder again if necessary.

Two diverging roads split from a common point and form an angle the point at which the roads diverge is the vertex an angle separates the area around it known in geometry as a plane into two regions the points inside the angle lie in the interior region of the angle and the points outside the angle lie in the.
To get started measure the side of the house directly under the gutter to determine its length in feet.

Make a mark with chalk and record the measurement.
The formula involves dividing 360 by the number of sides to calculate the corner angle.
For example if you have 30 feet of guttering the calculation is 1 4 x 3 0 75 i e.
Of these the miter joint is typically used to create a tight fit at both the inside and outside corners where two walls meet.
In the example the outside corner is 92 2 degrees.
Multiply the number of feet by 1 16 inch to determine the total slope the gutter requires.
As a general rule gutter slope is set at 1 4 inch per 10 feet of guttering.
For example if the gutter is 16 feet long the end near the down spout must be 1 inch lower than the starting end.
Divide this number by 2 to calculate the angle of the miter cuts for your moldings.
On a map you trace your route and come to a fork in the road.
Gutter installers a new product.
Then divide it by two to get the miter angle.
It s fine to use a calculator to figure the correct corner angles to cut for shapes with equal sides.
Run the tape measure from 1 corner of the gutter as far as you can go toward the opposite corner.
This means the downspout end of the gutter should be set 3 4 of an inch lower than the other end.
Tighten the pivot nut then remove the tool from the corner to read the angle in the digital display.
The most common methods of joining sections of baseboard molding include miter compound miter butt scarf and coped joints.
Carefully climb down the ladder and move it to the chalk mark.
