# Q2 W2 Nov 9-Nov 13 Pre-Algebra Teacher Stephanie Durrance 8th Grade Math (Pre-Algebra) 8th 2 Focus 5 – Pythagorean Theorem
Standard(s) Taught

MAFS.8.G.2.6: Explain a proof of the Pythagorean Theorem and it converse.

MAFS.8.G.2.7: Apply the Pythagorean Theorem to determine unknown side lengths in right triangles in real-world and mathematical problems in two and three dimensions.

MAFS.8.G.2.8: Apply the Pythagorean Theorem to find the distance between two points in a coordinate system.

Learning Targets and Learning Criteria

• demonstrate the relationship of the three side lengths of any right angle using visual models.
• apply algebraic reasoning to relate the visual model to Pythagorean Theorem.
• determine if a given triangle is a right triangle using Pythagorean Theorem.
• explain a proof of the converse of the Pythagorean Theorem.
• apply the Pythagorean Theorem to find an unknown side length of a right triangle.
• identify the hypotenuse as the side opposite the right angle in a triangle.
• draw a diagram and use the Pythagorean Theorem to solve real-world problems involving right triangles, including three- dimensional figures.
• connect any two points on a coordinate grid to a third point so that the three points form a right triangle.
• apply the Pythagorean Theorem with the characteristics of a right triangle to find the distance between the original two points.
