Common Core Math - Grade 8
Lesson Plan
Apply the Pythagorean Theorem to determine unknown side lengths in right triangles
Goals / Objectives
Use the Pythagorean Theorem to find the hypotenuse of a right triangle given both legs
Use the Pythagorean Theorem to find a missing leg of a right triangle given the hypotenuse and the other leg
Solve two-dimensional real-world problems by identifying right triangles within geometric figures (diagonals of rectangles, heights of isosceles triangles, distances across fields)
Solve three-dimensional problems that require applying the Pythagorean Theorem more than once (space diagonal of a rectangular prism, height of a cone given slant height)
Express answers in exact form using simplified radicals and as decimal approximations, choosing the appropriate form based on context
