1. Introductory Screen
Purpose: To give the title, developer’s name, and date of developing.
Text: The Pythagorean Theorem, Alaa Alkhamis, date of developing.
Image: No image needed.
2. Surprising fact
Purpose: To grab the learner’s attention and motivate him/her to learn about the
Pythagorean Theorem.
Text: Did you know that the Pythagorean Theorem is 2500 years old!
Image: Picture of Pythagoras.
3. Objectives
Purpose: To inform the learner of the objectives.
Text: In this presentation you will learn:
How to recognize right triangles and the hypotenuse.
The Pythagorean Theorem.
How to solve the Pythagorean Theorem equation.
How to use the Pythagorean Theorem in the real world.
Image: No image needed.
4. Recognizing right triangles and the hypotenuse
Purpose: Teaching the learner how to recognize right triangles and the
hypotenuse.
4.1: Text: This is a right triangle.
Image: A right triangle, highlighting the right angel.
4.2: Text: These are not right triangles.
Image: 2 non-right triangles.
4.3: Text: The longest side of a right triangle, opposite the right angle is called the
hypotenuse.
Image: Aright triangle, highlighting the right angle and the hypotenuse.
5. The Pythagorean Theorem
Purpose: To teach the learner the Pythagorean Theorem formula and how to
assign a, b, and c values to the correct side of the triangle.
Text: Here is the Pythagorean Theorem formula: a2+b2=c2, where a and b are two
sides of the triangle, and c is the hypotenuse.
Image: Picture of the Pythagorean Theorem formula, and a right triangle with
each side of it is labeled with (a, b, and c).
6. Example (1)
Purpose: To teach the learner how to solve the Pythagorean Theorem formula.
6.1: Text: In this right triangle, we have a=3, b=4, and we need to find c.
Image: Picture of a right triangle with each side of it is labeled with (3, 4,
and c).
6.2: Text: To find c, we will need to apply the Pythagorean Theorem: 32+42=c2
Image: same as 6.1, and then multi-slide showing the solution.
7. Learning check (1)
Purpose: To test the learner’s ability to solve the Pythagorean Theorem formula.
7.1: Text: Now it is your turn to try! Pause the presentation and try to find c value.
Image: Picture of a right triangle with each side of it is labeled with (5, 12,
and c).
7.2: Text: Solution (writing the steps of finding c value).
Image: Same as 7.1
8. Example (2)
Purpose: To teach the learner how to solve for any other missing side in a right
triangle.
8.1: Text: In this right triangle, we have a=6, c=10, and we need to find b.
Image: Picture of a right triangle with each side of it is labeled with (6, b,
and 10).
8.2: Text: To find b, we will need to apply the Pythagorean Theorem: 62+b2=102
Image: same as 8.1, and then multi-slide showing the solution.
9. Learning check (2)
Purpose: To test the learner’s ability to solve for any other missing value in a right
triangle.
9.1: Text: Now it is your turn to try! Pause the presentation and try to find a value.
Image: Picture of a right triangle with each side of it is labeled with (a, 12,
and 15).
9.2: Text: Solution (writing the steps of finding a value).
Image: Same as 9.1
10. Real world example
Purpose: To help the learner to apply the Pythagorean Theorem in real world
situations.
10.1: Text: Let’s say that you wanted to buy a case for your 9.7” iPad. The case
you found did not specify whether it fits the iPad, but it gives you
the length and width (10” * 7.5”). How can you use the Pythagorean
Theorem to know for sure that the case fits your iPad?
Image: Picture of an iPad and a case.
10.2: Text: The case is rectangular which means we can divide it into two right
triangles.
Image: Picture of a case with a drawing of two right triangles forming that
rectangular case.
10.3: Text: Solution (steps for applying the Pythagorean Theorem to find the case
diagonal “the hypotenuse”).
Image: Same as 10.2
11. Review

11.1 Text: Review. The Pythagorean Theorem formula.
Image: a2 + b2 = c2
11.2 Text: Review. Right triangle. The hypotenuse.
Image: Picture of a right triangle, highlighting the right angle and the
hypotenuse.
