Flying with Pythagoras
A lengthy narrative about Pythagoras and his students precedes an activity in which your young mathematicians practice using the Pythagorean theorem to solve three problems about flight and distance. Answers are provided.
Students are introduced to the Pythagoras' Theorem and its history, proofs and practice in application. Students find perimeters, areas and volume of everyday objects. Students state and explain the theory.
Gougu Rule or Pythagoras' Theorem
Fifth graders explore Pythagoras' Theorem. They examine the pattern linking the length of the hypotenuse of a right angled triangle and the length of the other two sides. Students find an unknown side in right angled triangles.
Poppy Meets Pythagoras
Eighth graders find connections between numbers in a table; use Pythagoras' theorem in a general algebraic form; and measure accurately from a scale drawing to find a method that might enable the helicopter to land inside a rectangular region.
What's My Angle, Pythagoras? (Pythagorean Theorem)
Students solve problems using the Pythagorean Theorem. In this geometry lesson, students solve for the missing angles of triangles. They apply ratios of the Pythagoras formula to solve for the missing side and angles.
In this triangles worksheet, students solve 40 problems in which Pythagoras' theorem is used to check if a triangle is right-angled. This page is intended for online use but may be completed on paper.
Learning Unit: The Pythagorean Theorem
Middle and high schoolers research the life of Pythagoras and the Pythagorean theorem. They write a short biography of Pythagoras and learn to apply the theorem in their study of right triangles.
Proving (a Theorem) and Disproving (a Theory)
As a cross-curricular instructional activity, your class examines the issues of gender discrimination, careers, and gender roles. They read and discuss an article, prepare a proof of the Pythagorean theorem as a class, and develop a creative representation of Pythagoras' ideas.
Hey, Pythagoras! Help Me Understand Your Theorem!
Learners explore the Pythagorean Theorem. In this math lesson, pupils solve problems using the Pythagorean Theorem. They select the appropriate numbers to substitute in the formula to solve problems.
The Radical Side of Pythagoras
Students solve real world problems using radicals and the Pythagorean Theorem. In this geometry lesson, students apply the concepts of trig ratios and right triangle to solve problems.
History / Introduction of Pythagorean Theorem
Learners explore Pythagoras and the history behind his theorem. They work together to solve a proof that is embedded in the lesson.
The Pythagorean Theorem
Students research the history of Pythagoras and the development of the Pythagorean Theorem. They write a research paper about Pythagoras. students use Microsoft Word to produce their paper.
Getting It Right!
Students construct right triangles, measuring the sides and recording the measurements in spreadsheets. They analyze their measurements for patterns and research the Internet for information on Pythagoras.
Learners prove the theorem of Pythagoras. In this Pythagorean Theorem lesson, students define the different parts of a right triangle. They use the Pythagorean Theorem to solve for the missing sides and angles of a right triangle.
The Search for Pythagoras' Treasure
Students identify and define properties of triangles. In this geometry lesson, students identify the missing sides and angles of right triangles. They use the rules of the Pythagorean Theorem to solve their problems.
Construction of the "Lute of Pythagoras"
Students explore the concept of the Lute of Pythagoras. In this Lute of Pythagoras lesson, students construct the Lute of Pythagoras on their Ti-Nspire. Students use circles, segments, lines, points, and regular polygons to construct the Lute of Pythagoras.
NUMB3RS Activity: To Pythagoras and Beyond
Students investigate the law of cosines. In this law of cosines lesson, students solve a problem based on a NUMB3RS episode. Students find the missing lengths of non-right triangles. Students determine if a triangle is acute, obtuse, or right using the Pythagorean Theorem.
In this Pythagoras' Theorem worksheet, students solve problems having to do with square roots and numbers to a certain power. Students match up the answers for 30 problems.
Calculating the Hypotenuse
In this triangles worksheet, students use Pythagoras' theorem to find the hypotenuse of a triangle. Students solve 20 problems and also calculate the length of the diagonals in rectangles. This page is intended for online use but may be completed on paper.
Getting It Right! An Investigation of the Pythagorean Theorem
Learners construct a variety of right triangles using a right-angled set square, cutting corners from pieces of paper or cardboard, and using dynamic geometry software. They measure the sides of these various right triangles and record measurements in a spreadsheet. Learners use the spreadsheet to look for possible patterns in the measurements. They also use the spreadsheet to square the values of each measurement and to look for possible relations among squared values.
