 Apply the Pythagorean Theorem to determine unknown side lengths in right triangles in real world and mathematical problems in two and three dimensions.





Use these to get information when you are working ahead or when you need to review a skill or concept.


 Do these activities and practice exercises to improve your skills and show proficiency.


A. I can apply the Pythagorean Theorem to find an unknown side length of a right triangle.

  How to Use the Pythagorean Theorem on Right Triangles


Write equations to represent right triangles using the Pythagorean Thm


Solve for Unknown Side Lengths Using the Pythagorean Thm (LZ)


8.G.7.A Wksh Practice


8.G.7.A Wksh 1

 Be sure to show the algebraic steps



8.G.7.A Wksh 2

Be sure to show the algebraic steps





B. I can draw a diagram and use the Pythagorean theorem to solve real world problems involving right triangles.










C. I can draw a diagram to find right triangles in a three-dimensional figure and use the Pythagorean Theorem to calculate various dimensions.










At the Analysis/ Knowledge Utilization Level of Reasoning:

(4) Student is able to demonstrate Proficiency (as shown below) and independently complete tasks at the higher reasoning level.


At the Comprehension/ Analysis Level of reasoning:

(3) Proficient: Student completes each level check, post-test and/or application independently with no major errors. 

(2) Partially Proficient:  With minimal help, student completes each level check, post-test and/or application.

(1) Not Enough Evidence:  With help, student shows a partial understanding of some of the simpler details and processes.

(0) No Evidence:  Even with help, no understanding or skill demonstrated.
