When 2 lines cross over each other they intercept each other forming certain types of angles
two intersecting lines cross where they are equal to each other. for example, y=x^2 intersects with y=4 at x=2 and x=-2 because when 4=x^2 x will equal (+/-)2
Their angles of intersection are the same, and the angles facing each other are supplementary.
If they measure 90 degrees then they are perpendicular. Other than that they are just intersecting lines
2 parralel lines are lines that are parallel to each other so they are oppoosite to eathother x
2 straight lines which cross over (intersect) each other Example: the letter x
When 2 lines cross over each other they intercept each other forming certain types of angles
Is parallel lines that don't cross
two intersecting lines cross where they are equal to each other. for example, y=x^2 intersects with y=4 at x=2 and x=-2 because when 4=x^2 x will equal (+/-)2
Their angles of intersection are the same, and the angles facing each other are supplementary.
Vertices.
If they measure 90 degrees then they are perpendicular. Other than that they are just intersecting lines
2 parralel lines are lines that are parallel to each other so they are oppoosite to eathother x
Parallel lines are 2 long straight lines that don't touch each other
2 things running beside each other, that will never cross no matter which way you go. For example,the top and bottom lines of a square. These 2 lines can extend infinitely in either direction and never intersect, therefore, they are parallel.
When the combined equation is a second degree equation in x and y. (x^2) + 2h.xy + (y^2) + 2g. x + 2f. y + c = 0
All 2-dimensional shapes. They may be closed or open, concave or convex, made of straight lines or curved ones, the lines may or may not cross each other.
