In this lesson, students explore the mathematics of architecture by investigating the unusual shapes of some of the rooms in the White House, such as the Blue Room's elliptical shape. They use a graph to plot, draw and determine the equation of an ellipse.

The purpose of this task is for students to practice using the ...

The purpose of this task is for students to practice using the equation of the circle in different ways. In each case, they must draw inferences from the information given and use the information to find the equation of the circle or to justify conclusions about the circle. They will use the distance formula to find the measure of the radius and the midpoint formula to find the center of a circle.

This purpose of this task is for students to connect their geometric ...

This purpose of this task is for students to connect their geometric understanding of circles as the set of all points equidistant from a center to the equation of a circle. In the task, students construct a circle using right triangles with a radius of 6 inches. This construction is intended to focus students on the Pythagorean Theorem and to use it to generate the equation of a circle centered at the origin. After constructing a circle at the origin, students are asked to use their knowledge of translations to consider how the equation would change if the center of the circle is translated.

This lesson unit is intended to help teachers assess how well students are able to: translate between the equations of circles and their geometric features; and sketch a circle from its equation.

Students will discover the equation of circles of the form (x â€“ ...

Students will discover the equation of circles of the form (x â€“ h)^2+ (y â€“ k)^2= r^2, where (h, k) is the center of the circle and r is the radius of the circle.

Students write the equation for a circle in center-radius form, (x - ...

Students write the equation for a circle in center-radius form, (x - a)2 (y - b)2 = r2 using the Pythagorean theorem or the distance formula. Students write the equation of a circle given the center and radius. Students identify the center and radius of a circle given the equation.
