In this geometry lesson, students collect and analyze data as they investigate relationships between the pre-image and the image of a triangle. They investigate angle measures, side lengths, and the dilation factor. The dynamic nature of Cabri Jr. allows students to form and verify conjectures regarding dilations.
High schoolers explore the concept of transformations. In this transformations lesson, students transform figures by reflection and rotation. High schoolers enter the coordinates into lists and transform the lists. Students transform a set of points that create an arrow.
Twelfth graders explore transforming matrices representing figures in the coordinate plane by entering data points of figures such as triangles and quadrilaterals into a matrix. High schoolers dilate, rotate, reflect, and translate the figures by multiplying by translation matrices.
