Rigid Motion Transformation and Angles
Introduction
ABC is the pre-image of FDE. In the first activity we identified the the transformation as rule.
Ry=0 T(x,y) (x-2,y-1).
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.
Question 1
What is the sum of the interior angles of a triangle?
Question 2
Do the angles of ABC and FDE sum to 180˚?
Question 3
Does a rigid motion transformation of ABC change the angle measures of FDE? 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?
Question 4
Finish the following statement in the space below. Write out the entire statement. 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.
