Midsegment Theorem Chapter 5 addition

Midsegment of a Triangle Connects the two midpoints of two sides of a triangle. Midsegment

Midsegment Theorem The midsegment connecting the midpoints of two sides of the triangle is parallel to the third side and is half as long. C E B D A DE // AB and DE = AB

TEST QUESTION (worth ~12% of your test grade) Verify that both parts of the Midsegment Theorem are true for segment DE. Show and label your work very neatly and clearly!

Conclusion is required for full credit!!! TEST QUESTION Show that DE // AB Find the slopes of segments AB and DE 8 6 4 The slopes are = so the lines are // 3 Conclusion is required for full credit!!!

Conclusion is required for full credit!!! TEST QUESTION 6 8 3 4 Show that DE = ½ AB Find the lengths of segments AB and DE Conclusion is required for full credit!!! 5 = ½ (10)
