Description
"How to determine whether triangles are similar" PPT courseware
Situation import
There is a thin line of unknown length. How can we quickly divide the thin line into five equal parts without measuring?
Explore
Straight lines l1 and l2 are intercepted by parallel straight lines l3 and l4, and the intersection points are A, B, C, and D respectively. Draw a straight line l5 ∥l4 through the midpoint E of line segment AB, and intersect l2 at point F. Point F is the center point of line segment DC The midpoint? If so, justify your conclusion.
Parallel Lines Bisector Theorem
A set of parallel lines, if the line segments cut on one straight line are equal, then the line segments cut on the other straight line are also equal.
Explore further
When two straight lines are intercepted by a set of parallel lines, the resulting corresponding line segments are proportional.
If the line segments intercepted by l1, l2 by l3, l4, l5 are not equal, does the conclusion just now still hold?
Basic Fact 9: The Proportional Theorem of Line Segments of Parallel Lines
Basic Facts 9 Inferences
A straight line parallel to one side of a triangle and intersecting the other two sides. The three sides of the resulting triangle are proportional to the three sides of the original triangle.
