QuestionDetermine if the following polygon pairs are always, sometimes, or never similar: $40.$ two obtuse triangles $41.$ a trapezoid and a parallelogram $42.$ two right triangles $43.$ two isosceles triangles $44.$ a scalene triangle and an isosceles triangle $45.$ two equilateral triangles

Studdy Solution
Two equilateral triangles are always similar because all their angles are equal (each angle measures 60 degrees), and their sides are in proportion (all sides are equal in length). Therefore, any two equilateral triangles will always be similar.
$$\text{Two equilateral triangles: Always similar}$$
