Will the 3-4-5 method work for making a table support

anglesupporttable

Instead of making a table support leg drop down vertically to the floor I wanted to make an angle (45 deg) support.

enter image description here

If I measure "A" from the floor to the table top and measure from wall to the end of table top…

Can I assume that "C" will correctly fit with a 45 deg angle at both ends?

NOTE: I could not get my graphic to make a 45, but I meant a 45 deg cut at both ends of "C".

No, 3-4-5 creates a right angle, not a 45 degree angle.

In your example, “a” must equal “b” for “c” to have 45 degree angle cuts at the ends.
