If two lines are parallel in a triangle
WebIf a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally. If D E ¯ ∥ B C ¯ , then A D D B = A E E C . Example : Find the value of x . The … WebSince parallel lines are lines that do not intersect when two lines are extended in a straight line, we can determine whether two lines are parallel or not as follows. If the two lines do not intersect when extended, they are parallel. Use Triangular Rulers to Make Perpendicular Lines and Parallel Lines
