Math-Angles formed by intersecting lines?
Q. Let's say you have two lines in the form of: y=mx+b y=nx+c They intersect at x(m-n)+b-c=0, or x=(c-b)/(m-n) and y=mx+b=nx+c. Here is the question: Given the two equations (ie, the values of m, b, n, and c), determine the angles formed by the two lines. You may use specifics to find angles. Here are some hints: Parallel lines have the same slope and never intersect. Perpendicular lines have slopes negative reciprocals of each other and form 90 degree angles. If you cannot prove it, try disproving. Develop proof enough to say that the values of m, b, n, and c have effects on the angles impossible to find angles for. First most detailed answer wins. Try finishing with a formula where theta is given in terms of m, b, n, and c.

A. Very interesting question. I will work on this in depth to see what I find, but for the rest coming, I think it will be better to solve this using triangles, if that gives a good hint. Peace

Q. infinite? that's what i think it is...
Asked by mizz kay - Wed Sep 3 18:44:44 2008 - - 1 Answers - 0 Comments

A. I think the intended answer is 2n. Consider the case n = 2. If I draw two intersecting lines, they split the plane into four pieces. Each piece has its corresponding angle at the intersection point. Four pieces, four angles. If I now draw another line through that point, two of the pieces I already have remain the same, the other two get cut in two. I now have six pieces and six angles to go along with them. If I draw another line, same story: four of the pieces I already have remain the same size, the other two get cut, for a gain of two pieces. It's like cutting a pizza: each time you cut you add two to the number of slices. Do it n times, get 2n slices, and 2n angles. Things get complicated if count not the number of angles,… [cont.]

A. Uh no. Parallel lines never intersect... However, I do believe it is true for perpendicular lines, because they will intersect.

A. It is impossible to know what it is that you are seeking from the question as it is worded. In simple terms, the measure of such an angle is - 25 ! Or, if you want it in circular measure 25 = pi( 25 / 180 ) = 0.1388 ...pi Otherwise, you will have to re-state the question more precisely.

I remember things in wierd ways so anything random or easy to remember will stick. adjacent angles-two angles with the same vertex sharing one side complementary angles-two angles, adjacent or nonadjacent, whose sum is 180 degrees. linear pair-adjacent angles that are supplementary vertical angles-opposite angles formed by intersecting lines. vertical angles are… [cont.]
Asked by EmmaL - Thu Feb 12 20:45:15 2009 - - 1 Answers - 0 Comments

A. adjacent- think of "add" therefore the angles have to TOUCH to add up complementary- these are angles that add up to 90 degrees, not 180. so when you think of complementary, think "right angle". Therefore, think to yourself...do these 2 angles add up to look like a corner of a paper? linear- think to yourself, do these angles make a LINE with each other? vertical angles- these are angles that form a "X" with each other and are opposite bisector- look at the word "bi" which means 2. Is there a line that makes 2 angles?
