9.5 Apply Compositions of Transformations Mrs. vazquez Geometry

g.co.2, g.co.5 Essential Question: What properties can there be when two transformations are combined? Objective: Students will be able to analyze properties of composite transformations.

Reflections in || Lines Thm If l1 and l2 are ||, then a reflection over l1 followed by a reflections over l2 is the same as a translation. *The distance between A and D are twice the distance between l1 and l2.

Reflections in || Lines Thm If a reflection over one intersecting line is followed by another reflection over the other intersecting line, then it’s the same as a rotation. *The m∡ of rotation is twice the m∡ of acute/∟ formed by the intersecting lines.
