1. Please read and do the investigation on page 273. Using geogebra, make a triangle. Then connect the midpoints of each side and figure out conjecture 42:
Three midsegments conjecture: The three midsegments of a triangle divide it into ______________________________________?
2. Now measure the lengths of each midsegment and each side. Figure out conjecture 43:
Triangle midsegment conjecture: A midsegment of a triangle is ______________
to the third side and ____________ half the length of the ________________.
3. Now do investigation #2 on page 274. Using geogebra, make a trapezoid. Then connect the midsegment of the non parallel sides. Measure the length of the three parallel sides. Fill in the last:
Trapezoid midsegment conjecture: The midsegment of a trapezoid is ______________
to the bases and is equal to the ____________________________________________.
