There are different levels of precision involved in creating the model of a geometric figure. Sketch implies freehand without tools. Draw produces a rough sketch with the aid of a straightedge. Construct requires the use of measurement tools such as a ruler, compass, or protractor. The main focus in Grade 7 lies with the construction of triangles and determining the number of possible triangles that can be formed given a set of three attributes. This objective investigates the possible combinations of attributes (SSS, SAS, ASA, AAS, SSA, and AAA) and determining when the conditions form a unique triangle, more than one triangle, or no triangle.
This activity set highlights Common Core State Standard 7.G.A.2 included in MATH-7 and Accelerated MATH-8.
