Stain Glass

In World History I learned about religion and the history of stained glass. The history of stained glass began in Ancient Mesopotamia. Stained-glass is windows in churches and monasteries in Britain and can be found as early as the 7th century. They were imported by workmen from France to glaze the windows of the monastery of St Peter. Stained glass was used in buildings during the renaissance period. Stained glass gained recognition from Christianity. In Geometry I learned about the properties of parallelograms and used the properties to design a piece of stained glass. The inspiration for my stained glass was to create a stain glass like Islam.. The shapes I included in my design were triangles, squares, rectangles, and rhombus. I made sure that my parallelograms abided by the properties of parallelograms which are opposite sides are parallel, opposite sides are congruent, consecutive angles are supplementary, diagonals bisect each other.

Sector Area and Arc Length Activity

For this activity we were given a cookie and had to find the sector area and arc length. We had to find the circumference of the cookie and also find the diameter of the cookie. We also had to find the angle measure of each sector's central angle. The total area of the four sectors of my cookie was 50 cm. My cookie did not add to the circumference of my cookie because each area length was different. Some arc length was small and the others were big. The 4 sector areas should add to the area of my circle because they are all sectors of my circle. Meanwhile they did not add to the circumference of my circle.
