Question

Triangle ABC is congruent to triangle GHE. To show this, I will describe the sequence of transformations needed to prove that they are congruent, starting with triangle ABC. First, rotate the triangle 90°
counterclockwise. This moves it to the first quadrant. Then, move all the points 5 units left and 1 unit up. These triangles are congruent, and the sequence of transformations is rotation(90 degrees CCW), then translation(-5, 1). chane this into different words. answer in a 8th graders words

Answer 1

Start with triangle ABC. First, turn it a quarter turn to the left (rotate it 90° counterclockwise). That moves the triangle up into the upper-right area of the grid. Next, slide every point of the triangle 5 units to the left and 1 unit up. After those two steps the triangle lines up with triangle GHE, so the two triangles are the same shape and size (congruent).
