## Watch Your Head... Hanging a ceiling is simple. The screws go in the drywall just showing a dimple. | ## Power tools Crown molding, baseboards, bookcases, and stools to name a few. Using math to finish projects is not something new. | ## Insulation Putting insulation behind the wall. I'm being so careful not to fall. |

From a square…….

By Madison Jasv

*Right Angles* seem to frame my life

At 90% degrees and *perpendicular lines *

Yet my *equation* was never understood

Just a *midpoint* on an imaginary line

Left blank hoping for another to find

There our steps travel *parallel*

But yours *reflects* a shadow that never fails

It keeps me suspended in *inequalities*

*Isolated* in the *zeros* you trace

Giving me nothing that ought to be

Leaving me treated as an *empty set*

Another *geometric shape* to always forget

Why don’t you slice across on the *diagonal line*

Two *triangles* your needing to find

Already *bisected* to the *interior*

Left me a *Fraction* more than inferior

With* Angles *that trap me in a world of 360

A place where your eyes can see right through me

It’s there I stand alone on my *vertices*

To *prove* I am more than *congruency*

But to hear your *hypothesis*

Breaks me down to my *intercepts*

And I *shrink* on the* plane*

In the silence of my forgotten name

The lonely *perfect square*

Yet *dependant* upon your care

## Quilting Project

## Geometry Unit 4Our quilt design shows several things, a circle inscribed within a square, sectors, a radius intersecting a line forming a right angle at the point of tangency, and arc length. It should be easy for anyone to measure the radius (6 inches) and find the area of the circle, sector, and arc length. Now completed, we are pleased with our quilt. Getting precise measurements can be difficult. You can't just look at a piece of fabric and cut. To get the most area your pattern should be placed strategically onto the fabric. Folding on a line of symmetry was very helpful. It not only saved time but made measuring easier. | ## Geometry Unit 4Our group made a quilt based on the circles unit.We used 12 patterns of red, orange, and yellow cut into rectangular strips to sew together. We knew we needed to cut these strips to be 1 inch long. Once sewn we made a tube by sewing the ends together. We then ripped consecutive seams ensuring that the pattern was followed. We cut these sections of fabric into trapezoids to make a circle on the white background. We found directions for making a spiral on a much larger scale so we had to greatly alter the measurements to create a spiral on a much smaller scale. We measured 10-degree angles using a protractor before creating the trapezoids. The legs of the trapezoids represent the radii of the circle. We sewed isosceles triangles together to create the frame for the quilt. We used two black and white fabrics with circular designs. The isosceles triangles with the black background have concentric circles. We added a gray square to each corner. | ## Algebra We all agreed to illustrate Pascal's Triangle. Pascal's triangle helped us to find the coefficients of each term when expanding polynomials. Each row represents the coefficients of a binomial expression (x + y) raised to a power. We learned that the number of terms is always one more than the exponent. The first and last terms have a coefficient of 1. The second and next to the last term have coefficients with values the same as the power of the binomial. Each row is made from the sum of the two numbers above it in the previous row. The numbers in each row are also symmetrical. We found something interesting about the patterns. The sum of each row is 2 raised to a power. |
