True or False questions

Any two rectangles are similar:

False, because rectangles don’t always look the same. Although, all rectangles have to have the same lengths on the corresponding sides. As the picture shows, both rectangles have the same lengths on all the corresponding sides. The rectangles do not necessarily have the same size or shape.

Any two equilateral triangles are similar:

True, because all equilateral triangles have the same shape. All sides of an equilateral triangle needs to be equal to each side and all angles must be 60 degrees. No matter what size an equilateral triangle is, it will always stay the same.
