Pythagorean Theorem and Its Converse

Curated and Reviewed by Lesson Planet

Make sure it is all right in class. Pupils review the Pythagorean Theorem and find sides of right triangles, either by simplifying radicals or using calculators to find approximate lengths. Learners find out how to use the converse to determine whether a triangle is right, obtuse, or acute. Scholars practice their use of the Pythagorean Theorem and its converse and apply them in the included worksheets.
