What is the Relationship between Dilations and Angles in Geometry
Practice Questions: If \(\angle A\) in Triangle \(ABC\) is \(40^\circ\) and Triangle \(DEF\) is a dilation of Triangle \(ABC\), what is \(\angle D\) in Triangle \(DEF\)? A pentagon \(ABCDE\) has \(\angle A = 108^\circ\). If Pentagon \(A’B’C’D’E’\) is a dilation of Pentagon \(ABCDE\), what is \(\angle A’\)? \(40^\circ\) \(108^\circ\)
How to Understand Dilations: A Step-by-Step Guide
Examples Practice Questions: Dilate the point \(C(3, 2)\) about the origin using a scale factor of \(3\). Dilate the point \(D(6, 7)\) about the origin using a scale factor of \(0.25\). \(C'(9, 6)\) \(D'(1.5, 1.75)\)
