Midsegment Theorem Chapter 5 addition
Midsegment Midsegment of a Triangle • Connects the two midpoints of two sides of a triangle.
C DE // AB and DE = AB D E A B Midsegment Theorem • The midsegment connecting the midpoints of two sides of the triangle is parallel to the third side and is half as long.
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!
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!!!
8 6 4 3 TEST QUESTION • Show that DE = ½ AB • Find the lengths of segments AB and DE Conclusion is required for full credit!!! 5 = ½ (10)
