Based on your description, we need to compare the features of Figure 1, which is described as an isosceles triangle with a base of 2 units and a height of 2 units, to the other figures to find a similar one.
- Figure 1: Isosceles triangle, base = 2 units, height = 2 units.
- Figure 2: Inverse isosceles triangle, base = 2 units, height = 3 units.
- Figure 3: Parallelogram.
- Figure 4: Triangle, base = 3 units, height = 3 units.
- Figure 5: Isosceles triangle, base = 2 units, height = 2 units.
Figures with the same proportions or shape can be considered similar. Figure 1 and Figure 5 both have the same dimensions (base of 2 units and height of 2 units) and are both isosceles triangles.
Thus, Figure 5 is similar to Figure 1.
