Pythagorean Theorem - Model the Pythagorean Theorem.
0806.4.2 Pythagorean Theorem Converse - Use the converse of the Pythagorean Theorem to determine if a triangle is a right triangle. 0806.4.3 Measurement Instrument - Select or use the appropriate measurement instrument to determine or create a given length, area, volume, angle, weight, or mass. 0806.4.4 Precision and Accuracy - Understand how the precision of measurement influences accuracy of quantities derived from these measurements. 0806.4.5 Congruent and Supplementary - Analyze the congruent and supplementary relationships of angles formed by parallel lines and transversals (such as alternate interior, alternate exterior, corresponding, and adjacent). 0806.4.6 Make Conversions - Make within-system and between-system conversions of derived quantities including distance, temperature, and money. 0806.4.7 3-Dimensional Figure - Visualize or describe the cross-section resulting from the intersection of a plane with a 3-dimensional figure. 0806.4.8 2-D and 3-Dimensional Figure - Build, draw, and work with 2- and 3-dimensional figures by means of orthogonal views, projective views, and/or nets. SPI 0806.4.1 Use the Pythagorean Theorem - Use the Pythagorean Theorem to solve contextual problems. SPI 0806.4.2 Find Distance - Apply the Pythagorean theorem to find distances between points in the coordinate plane to measure lengths and analyze polygons and polyhedra.
