1. Please do the investigation on page 256. Use geogabra to create three polygon that look somewhat like the three in the book. Then measure the angles and share out.
At about 9:35 we should as a class answer the three conjectures on page 256 and 257:
Quadrilateral sum conjecture: The sum of the measure of the four angles of any quadrilateral is__________________.
Pentagon sum conjecture: The sum of the measure of the five angles of a pentagon is ________________.
Polygon sum conjecture: The sum of the measures of the n interior angles of an n-gon is
_______________________.
At about 9:50 please start the investigations on page 260 using geogebra again.
