Translated and Dilated Circles
Loading the math board and drawing, please wait…
This example demonstrates the geometric phenomenon of translating and dilating circles. Key mathematical concepts include circle geometry, transformation and scaling relationships. Construction involves GeoGebra commands such as h, k, r, L_1, L_2, L_3, L_4 for translating centers and adjusting radii. Suitable for high school students learning geometric transformations and coordinate geometry applications.
GeoGebra Commands & Parameters
10…11…101…10(x - h)^(2) + (y - k)^(2) = r^(2)(x + h)^(2) + (y - k)^(2) = r^(2)(x - h)^(2) + (y + k)^(2) = r^(2)(x + h)^(2) + (y + k)^(2) = r^(2)
AI Drawing Prompt Reference
Draw two circles. The first circle has its center at the origin with a radius of 1. The second circle is translated to a center at (h, k) with the same radius. Then, dilate the second circle by scaling its radius to twice the original. The relationship between the circles involves translation and scaling. The construction order is to draw the base circle, then translate the center, and finally adjust the radius.
