8M03A Pythagoras' theorem - Ochre Education

This unit of work focuses on Pythagoras' theorem. Students define and identify the hypotenuse of a right-angled triangle as being the longest side and opposite the right angle and the perpendicular sides as being the shorter two sides and adjacent to the right angle; define Pythagoras' theorem in words and symbols; use the converse of Pythagoras' theorem to determine if a triangle is right-, acute-, or obtuse-angled and if a set of three integers is a Pythagorean triad; use Pythagoras' theorem to find unknown lengths in right-angled triangles using two known side lengths including the case of an isosceles right-angled triangle giving lengths in exact root form or approximated by rounding; rich task on Pythagoras' theorem.
