Geometry Copy “measurements of the earth” points lines planes polygons polyhedra must often draw and add measures to a diagram to show work angles are always measured in degrees (don’t forget the symbol) use the notation sheet (not the textbook) as a guide for notation use the pi 𝜋 button on your calculator; do not use 3.14 or 22 7 pass along exact values; wait to round until you state an answer 12A, 12B, 13A, 13B 5/2/2019 9:00 PM
