Mathematics MA2015 (2016) Grade: 9-12 Geometry | 17 ) Prove theorems about triangles. Theorems include a line parallel to one side of a triangle divides the other two proportionally, and conversely; and the Pythagorean Theorem proved using triangle similarity. [G-SRT4] |
Mathematics MA2019 (2019) Grade: 9-12 Geometry with Data Analysis | 26. Verify experimentally the properties of dilations given by a center and a scale factor.
a. Verify that a dilation takes a line not passing through the center of the dilation to a parallel line, and leaves a line passing through the center unchanged.
b. Verify that the dilation of a line segment is longer or shorter in the ratio given by the scale factor. Unpacked Content
