Section 9.1 The Pythagorean Theorem 467 Classifying Triangles Verify that segments with lengths of 4.3 feet, 5.2 feet, and 6.1 feet form a triangle. Is the triangle acute, right, or obtuse?

Using BLM 4.1.1, pairs of students will prepare a set of tag board paper strips if geo-strips are not available. Using BLM 4.1.2, students will explore all of the ways that two intersecting paper strips or geo-strips can be positioned to create different quadrilaterals. Class/Group collaboration to complete BLM 4.1.2 or each pair selects one
