#### Proof of the Pythagorean Theorem Using Transformations

Middle and high schoolers construct a triangle using Cabri Jr. They construct squares on each of the legs and hypotenuse of the triangle. Pupils show that the area of the squares on the leg equal the area of the square on the hypotenuse.

#### The Trigonometric Ratios: Lesson

SOH, what is this thing called trigonometric ratios? A section of an extensive playlist on geometry identifies the adjacent and opposite sides in relationship of an angle. Using the identified sides, the video defines the sine, cosine,...

Lesson Planet

#### Pythagorean Explorer

Make sure the measurement is right. The interactive provides right triangles with a missing side measurement. Pupils use the given sides and the Pythagorean Theorem to calculate the length of the missing side. After entering the length,...

#### Altitude to the Hypotenuse

Gain some altitude with the geometric mean. Pupils discover the relationship between the three triangles formed by drawing the altitude to the hypotenuse in a right triangle. The lesson introduces the geometric mean and provides problems...

Lesson Planet

#### Identifying the Sides of a Right Triangle

Find the right way to identify sides of right triangles. Scholars learn to correctly label the sides of a right triangle in the second video in a series of 16. The exercise is in preparation for determining trigonometric ratios.

Lesson Planet

#### The Pythagorean Theorem

Be sure the class gets this one right. Using a right triangle, the video introduces the Pythagorean Theorem. The presentation breaks down the theorem into its components while providing uses of the Pythagorean Theorem and its converse.

Lesson Planet

#### Geometric Mean Proof

Mean is an average, but what is the geometric mean of two line segments? Scholars prove that the altitude to the hypotenuse is the geometric mean of the two parts of the hypotenuse. But first, they must explain why the two triangles...

Lesson Planet

#### Justifying HL Congruence

What is so special about right triangle congruence? Pupils use what they know about transformations and right triangles to develop a proof of hypotenuse-leg congruence. The proof provides the given of two angles that measure 90 degrees...
