To get the most from a direct box, your mixing board must have balanced mic and/or line inputs! (Note that some mixers offer both XLR and 1/4 balanced inputs -- check your manual.) Use a direct box if you are experiencing hum, buzz, or radio interference, or if your instrument's cable is longer than 20 feet.
When a transversal (any line that passes through two parallel lines) cuts two parallel lines then the angles that correspond to the similar positions (angles in the matching corners) with respect to either of the parallel lines and lie on the same side of the transversal are called the Corresponding angles.
Let us see this with some examples. Two angles in math are said to be corresponding when they are being referred in a way of equality. Angles made by two Parallel Lines when they are cut by a transversal or the angles when formed in an Isosceles Triangle are the Corresponding Angles. In both cases corresponding angles are equal in measure.
