The Perfect Face

For today, we will be doing a web-quest to discover the Golden Ratio!

Click here to get started!

And don't forget - quiz tomorrow over all the sequence stuff we have been doing.  You can check your work on the inductive/deductive reasoning worksheet here.

Parallelogram Practice

Today we will be practicing the properties of parallelograms.  Please click on this link to access the worksheet.  You will need to copy all problems onto your own sheet of paper and submit your work at the end of the period.

Theorems for Monday

Your homework over the weekend is to copy the following theorems into your notes.  We will be using these theorems in class on Monday.

Pop Quiz Tomorrow

Tomorrow we will have a very short quiz over the formal names of certain polygons as well as the ability to identify and construct concave vs convex polygons.  You will also need to be able to apply both the Interior and the Exterior Angle Sum Theorems.

You can access the prompt here.

On the lighter side of things, here is a little song to help you remember all of the named polygons.

Logic Puzzle Project

Logic Project

Logic puzzles involve a variety of logic statements.  Some are stated in the clues while others are implied.  Your task is to create your own logic puzzle.  It must include:

• A story to introduce the problem.  This should contain a scenario that makes the puzzle compelling.  You should have 5 characters involved in your story.

• 2 categories each with 5 variables

• Between 3 to 5 clues!  Remember, clues should work together, not be obvious and simple.  Get creative!

While every puzzle should be solvable, you do not want to make the puzzle too obvious.  Every puzzle must be accompanied by a grid made in Google Sheets and a solution key on a separate sheet in the same workbook.  You may wish to have a classmate attempt to solve your puzzle to see if your clues are clear and sufficient.  

I've provided a template here.  You will need to save a copy of this template to your drive so you can edit it.  Once you have done that, make sure to share it with me (rrmcadam@cps.edu) through google drive!

All spreadsheets must be submitted via google drive by February 28th, no later than 7:59 am.  Do your best and show off your talent J

Below is the rubric that I will be using to grade your project.  Make sure you have all of the necessary pieces.

Ch 5 Review Solutions

You can find the solutions to the review here!  The solution to number 27 is here!  Note that with #27, we can show that the triangle is a right triangle because two sides have opposite reciprocal slopes and we also know that the orthocenter of a right triangle lies on the vertex of a right angle.

You can find solutions to yesterday's practice here.

You can also find some extra online practice here:

• Slopes of Parallel and Perpendicular Lines
• Midpoint Formula
• Perpendicular Bisector Theorem
• Midsegments of Triangles
• Triangles & Bisectors
• Identify medians, altitudes, angle bisectors, and perpendicular bisectors
