 In a plane, 2 congruent figures can be mapped onto one another by a composition of at most 3 reflections. Theorem 3-3 A composition of reflections in 2 intersecting lines is a rotation. Theorom 3-2 The only 4 isometries are... reflection, translation, rotation, and glide reflection. A composition of reflections in 2 parallel lines is a translation. Theorem 3-1 There are only 4 isometries. They are reflection, translation, rotation, and glide reflection. Theorom 3-4 Isometry Classification Theorem an isometry that does not change orientation is a... rotation A translation is an isometry that does not change... orientation A change made to the position, shape, or size of a figure is a... Transformation A composition of reflections in 2 parallel lines is a... translations An isometry is a transformation in which the original figure and its image are... congruent An isometry that changes a figure's orientation is a... reflection A figure has symmetry if... there is an isometry that means the figure onto itself. A transformation that moves points the same distance and in the same direction is a... translation Every triangle and quadrilateral ___________. tessellates A composition of reflections in 2 intersecting lines is a... rotation A dilation maps figures to... similar figures A plane figure has reflectional symmetry, or line symmetry if... there is a line in which the figure is reflected onto itself. Tessellations can have many kids of symmetries, including... trnslational symmetry and glide reflectional symmetry. If a plane figure can be mapped onto itself by a rotation of 180 defrees, it has... point symmetry A figure has rotational symmetry if... there is a rotation of 180 degrees or less that maps the figure onto itself. A repeating pattern of figures that completely covers a plane without gaps or overlaps is a... tessellation or a tiling What maps the tessellation onto itself? A glide reflection and a translation You can use scalar multiplication to find the image of a figure under a dilation centered at the orgin in... the coordinate plane. The dilation is an enlargement when... the scale factor is greater than 1. A similarity transformation is a... dilation The dilation is a reduction when... the scale factor is less than 1. An entry is... each item in a matrix An enlargement is... the image is larger than the original figure. Composition is... any 2 transformations in which the second transformation is performed on the image of the first transformation. A reflection reverses orientation. A reflection is an isometry. Properties of a Reflection A rotation is an isometry. A rotation does not change orientation. Properties of a Rotation A translation is an isometry. A translation does not change orientation. Properties of a Translation A design that repeats itself along a straight line is a... frieze pattern
