Learning Target: By the end of today’s lesson we will be able to successfully use drawing tools and matrices to draw dilations. Enlargement vs Reduction: (k) Ex 1: Find the scale factor of the dilation. Then tell whether the dilation is a reduction or an enlargement. a.) b.) = ______, = ______, Scale Factor, = ______ . Scale Factor, = ______. k k The image is a(n)__________________. The image is a(n) _________________. P′ P’ c.) Find the of x. = ______, Factor, = ______ . k The image is a(n)__________________. P′ Find x: x = ______. Ex 2: Simplify the product: b.) c.) Ex 3: The vertices of quadrilateral are (–3, 0), (0, 6), (3, 6), and (3, 3). Use scalar ABCD A B C D multiplication to find the image of after a dilation with its center at the origin and a scale ABCD factor of Graph and its image. ⅓. ABCD
