[math]\Delta[/math][color=#ff0000][i]ABC is the pre-image of [math]\Delta[/math]FDE. In the first activity we identified the the transformation as rule. [br][br] R[sub]y=0[/sub] [math]\circ[/math]T(x,y) [math]\longrightarrow[/math][/i][/color] [color=#ff0000][i](x-2,y-1).[br][br][/i][/color][color=#ff0000][i]The measure of each angle has been identified in the triangle.s Please answer the questions below about the distances of the sides of the triangles.[/i][/color]
[color=#ff0000][i]What is the sum of the interior angles of a triangle?[/i][/color]
[color=#ff0000][i]Do the angles of [math]\Delta[/math]ABC and [math]\Delta[/math]FDE sum to 180˚?[/i][/color]
[color=#ff0000][i]Does a rigid motion transformation of [math]\Delta[/math]ABC change the angle measures of [math]\Delta[/math]FDE?[br][br]Another way to word the question: After reflecting over the x-axis and translating left then down, did the measure of the angles in the triangle change?[/i][/color]
[color=#ff0000][i]Finish the following statement in the space below. Write out the entire statement.[br][br][/i][/color]If a shape is transformed then the angles of the shape are _____________________ . If the angle remains ___________ then the shape is the ________________ (same or different) shape.
