This was definitely a great resource for my students who struggle with math finish out their school year! Everything is there, ready to go! They really like the format of these notes as well! (Very AVID friendly!)
This resource has been exceptional. This allows me to help my students put together useable notes and build an understanding before moving to the next concept. Well put together and very clear and concise!

I thoroughly love the way you have the units designed. The examples cover all possibilities. And the fact that the pictures are there, helps so much. It saves time and there is plenty of room to show the work and put extra information that the students need to know or remember.

Pythagorean Theorem. In the case of a right triangle, a²+b²=c². Converse of the Pythagorean Theorem. If the angles are summative in terms of a²+b²=c², it is a right triangle. Pythagorean Triple. Three integers that, as side lengths of a triangle, form a right triangle (Ex. 3/4/5 or 5/12/13) 3-4-5. Pythagorean Triple.
For a right triangle, the theorem states that a 2 + b 2 = c 2 a^2 + b^2 = c^2 a 2 + b 2 = c 2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides Step 4 Square the lengths of the two shorter sides (AC and BC) and add them together.

To determine whether a given triangle is a right triangle, we can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides

Finding a missing side. In a right triangle a = 7 and c = 25, let's find the length of the third side.. We can start by substituting what we know into the Pythagorean Theorem and then solve for the unknown side, b: 7 2 + b 2 = 25 2 49 + b 2 = 625 b 2 = 576 b = 24. Now, let's find the length of the third side of the triangle below and leave our answer in reduced radical form.. Since we are ...
