Cut the Angled Shelf Ends
For the outer ends of the shelves, cut across one end of each board at a 45-degree angle, with the angle of the saw's blade also set to 45 degrees for the mitered edge strip (this is called a compound cut). Cutoffs on long boards are easier to do with a circular saw than with a table saw.

Also question is, how do you calculate the angle of a shelf support?

How to Determine the Angle for Braces for a Shelf

1. Measure the shelf's depth, which is the distance it extends from the wall.
2. Hold a carpenter's level below the shelf perpendicular to the wall.
3. Measure the horizontal distance along the level between the wall and the front of the shelf.
4. Divide the second measurement by the first.

One may also ask, how do you determine the angle of a cut? The formula involves dividing 360 by the number of sides to calculate the corner angle. Then divide it by two to get the miter angle. If you're making a five-sided project with all sides equal, you divide 360 by five to get 72 degrees. So each joint or corner forms a 72-degree angle.

Regarding this, how do you measure angles?

How to measure an angle with a protractor:

1. Place the midpoint of the protractor on the VERTEX of the angle.
2. Line up one side of the angle with the zero line of the protractor (where you see the number 0).
3. Read the degrees where the other side crosses the number scale.

What angle do you cut wood to make a circle?

cut wood strip longer than radius of circle Put a pencil through the other hole, and pivot the piece of wood 360 degrees to draw a circle.

### What are the angles of an equilateral triangle?

You'll notice that along with this triangle's sides, its three angles are also all equal. Since the sum of a triangle's angles is always 180 degrees, each angle in an equilateral triangle must measure 60 degrees. This is because we must divide 180 degrees evenly between the three angles: 180 / 3 = 60.

### How do you cut angles on wood?

How to Cut Angles in Wood
1. Set the first piece of molding in the miter box and hold it in place.
2. Put the saw in the appropriate slots, setting the angle.
3. Cut the wood carefully, without rushing.
4. Place the second piece of wood in the miter box and hold it in place.

### How do you cut an obtuse angle on a miter saw?

A 135 degree angle is an OBTUSE angle. The miter for this corner is 67 1/2 degrees. That's easy to cut on your miter saw. Just set the saw at 22 1/2!

### How do you hang a shelf without a drill?

Method 1 Using Adhesive Mounting Strips
1. Get a shelf made of a light, hollow material.
