Question 4: Use the Visual to...
Think about it. Could you use the Pythagorean Theorem to find the missing sides of these two triangles? Why or why not? Hint: Notice what is different about these two triangles compared to the triangles from the previous questions.
Question 4: Check your answer.
Visual 5: Click and drag the points to explore relationships between the sides of the triangle and the areas of the squares.
Question 5: Use the Visual to...
Determine if each triangle follows the Pythagorean Theorem (or not), and find the angle measurements.
If a triangle follows the Pythagorean Theorem, what does it have?
How can you tell if a triangle is a right triangle (or not) without looking at it?
