Geometry and Measurement

In solving a problem, use the strategy that works best for you. Try different strategies and find one that suits your own problem-solving style.

In this unit, you will learn to choose the appropriate unit of measurement. You will identify more precise measurements, and locate places using map coordinates and latitude and longitude. Practice drawing, measuring, and identifying angles. Begin to recognize and construct parallel and perpendicular lines. You will classify polygons, and represent three-dimensional shapes in a drawing.

Terms to be familiar with in this unit include:

U.S. customary units	metric system	precision	significant digits	absolute position
relative position	angle	vertex	line	line segment
endpoints	ray	straight angle	right angle	acute angle
obtuse angle	complementary	supplementary	congruent	angle bisector
parallel	perpendicular	perpendicular bisector	transversal	interior angle
exterior angle	alternate angle	corresponding angle	vertical angle	polygon
triangle	quadrilateral	pentagon	hexagon	heptagon
octagon	Venn diagram	equilateral triangle	isosceles triangle	scalene triangle
parallelogram	rectangle	rhombus	square	trapezoid
diagonal	regular polygon	convex polygon	concave polygon

Below are the geometry projects we will work on in eighth grade.
