Parallel lines in a triangle
WebThe basic proportionality theorem, also known as the Thales theorem states that "the line drawn parallel to one side of a triangle and cutting the other two sides divides the other two sides in equal proportion ". For example, in the given figure, line DE is drawn parallel to side BC, such that it joins the other two sides, AB and AC. WebThe side splitter theorem can be extended to include parallel lines that lie outside a triangle. If a line lying outside a triangle is parallel to one side of the triangle and intersects the extensions of the other two sides of the triangle, then the line divides the …

WebLinear pair. 2 Adjacent angles whose non-shared sides are opposite rays. Vertical Angles. Two non-adjacent angles formed when 2 lines intersect (vertical angles are congruent) Corresponding Angle Postulate. If two parallel lines cut by a transversal, then each pair of corresponding angles are congruent. Alternate Interior Angles Theorem. WebThe side splitter theorem states that if a line is parallel to a side of a triangle and the line intersects the other two sides, then this line divides those two sides proportionally. The side splitter theorem is a natural extension of similarity ratio, and it happens any time that a pair of parallel lines intersect a triangle. Diagram 1

This construction works by creating any triangle … WebExamples Triangles. In a triangle, four basic types of sets of concurrent lines are altitudes, angle bisectors, medians, and perpendicular bisectors: . A triangle's altitudes run from each vertex and meet the opposite side at a right angle.The point where the three altitudes meet is the orthocenter.; Angle bisectors are rays running from each vertex of …
