Graphic Descriptions – Pythagorean Theorem - Week #7
1. Title Page
Purpose: Slide with the title of the video and developer’s name (Ryan).
Text: Pythagorean Theorem, Developer’s Name, and development date.
Image: none
2. Introduction to the topic of Pythagorean Theorem
Purpose: Introduce the video as being about a mathematical formula
Text: Mention Pythagorean Theorem
Image: A single right triangle illustrating the correct 90° notation.
3. Triangles
Purpose: remind audience about triangle terminology.
Text: Scalene, isosceles, right triangle.
Image: triangles representing scalene, isosceles, and right triangles
4. Right Triangles
Purpose: remind audience what a right triangle is. Mention that angles must sum to 180.
Text: Right triangles are named for their right angle. A right angle means that the angle
measures 90°. A triangle can only have at most one right angle. This is because all the
angles sum to 180°.
Image: A single right triangle illustrating the correct 90° notation.
5. Right Triangles
Purpose: To get the audience to be able to see right triangles even if the shape is upsidedown or lying on its hypotenuse
Text: All of these shapes are right triangles. Do you know why?.... You guessed it! They
all have one right angle.
Image: Several right triangles in various positions
6. Connection to the Past
Purpose: Introduce Pythagoras and his Theorem.
Text: Pythagoras spent much of his life on a quest for knowledge, and what he
discovered, was that there is a special relationship in the sides of a right triangle.
Image: A single right triangle illustrating the correct 90° notation.
7. Guided Practice (3-4-5 triangle)
Purpose: Provide a guided example that students can follow along to.
Text: The steps to solving the length of the triangle using the Pythagorean Theorem
Image: A 3-4-5 right triangle with the right angle and all sides labeled
8. Learning Check #1 and “How'd you do?” (Learning Check Feedback)
Purpose: Provide a learning check that students can complete with feedback after
completion.
Text: Show 𝑎2 + 𝑏 2 = 𝑐 2 and all the steps to solve for feedback.
Image: A right triangle in a different orientation
9. Real World Application example
Purpose: To show a practical application.
Text: Show 𝑎2 + 𝑏 2 = 𝑐 2 and all the steps to solve a real world problem. Maybe
involving a kite and the height of a building.
Image: A building with a right triangle next to it and all the steps visually laid out
10. Learning Check #2 and “How'd you do?” (Learning Check Feedback)
Purpose: Provide a learning check that students can complete with feedback after
completion.
Text: Show 𝑎2 + 𝑏 2 = 𝑐 2 and all the steps to solve for feedback.
Image: A computer monitor or tv screen. Following slides will illustrate a triangle hidden
in the monitor
11. Extra Practice
Purpose: Provide an opportunity for optional extra practice
Text: Show 𝑎2 + 𝑏 2 = 𝑐 2 and all the steps to solve for feedback
Image: A right triangle lying on its hypotenuse with the correct 90° notation.
12. Credits
Purpose: To thank the individuals involved with the instructional video.
Text: Instructional designer, funding agent, and subject-matter expert names.
