![]() Rotate segment \(CD\) 180 degrees around point \(E\). Draw its image and label the image of \(C\) as \(A.\) Rotate segment \(CD\) 180 degrees around point \(D\). The coordinates of point \(E\) are \(E\)(5 comma 5). ![]() Tell them that they will investigate this further in the next lesson.ĭescription: Point \(E\) and line segment \(\overline\) are: \(C\)(2 comma 2), \(G\)(4 comma 3) and \(D\)(6 comma 4). Some students may say that they “look parallel” while others might try to reason using the structure of the grid. Watch for how students explain that the \(180^\circ\) rotation of segment \(CD\) in the second part of the question is parallel to \(CD\).
