Write a paragraph describing the relationship between triangles and circles. Be sure to include a description of the different centers a triangle can have. Answer: All triangles contain circles on the inside and out. There are circles found on the outside called circumscribed circles which should touch all vertexs of the triangle. Inscribed circles are found on the inside of a triangle they touch each side of the triangle at a point.
Standardized Test Students of all ages are getting their number-two pencils sharpened and finest energy drinks ready in order to stay alert and prepared for all the standardized tests they will soon be encountering. For the last 50 years, standardized tests have been a way to measure students academic knowledge. But are standardized tests a proper tool for measuring student readiness? Standardized test are a problem because there are so many different factors that determines how well a student does on the test. Passing a standardized test is a skill that can be taught, but does not truly measure what a student has learned in the classroom; therefore standardized tests should not be used as a tool to measure students knowledge because students have more to offer than just filling in bubbles.
