Use the image to answer the question.
An illustration shows a 12 by 8 grid with 3 isosceles triangles on it. Figure 1 extends from the top of the 3rd to the end of the 4th rows, and from the start of the 3rd to the end of the 4th columns. The base is 2 units and the perpendicular height is 2 units. Figure 2 extends from the top of the 3rd to the end of the 4th rows, and from the start of the 9th through the 10th columns. The base is 2 units and the perpendicular height is 2 units. Figure 3 extends from top of the 4th to the end of the 6th rows, and from the start of the 5th to end of the 8th columns. The base is 4 units in length and the perpendicular height is 3 units.
Which figure is similar to Figure 1?
