Are a scalene triangle and an isoceles triangles sometimes always or never similar?
Sometimes similar but it depends
Are circles sometimes never or always similar?
Circles are congruent when they have the same radius and they are similar when their radii are different in lengths.
Can similar triangle the ratios of all three pairs of corresponding sides are never equal?
No. In similar triangles, the ratios of the 3 pairs of corresponding sides are always equal.
Are two circles sometimes always or never similar to each other?
They can b different sizes
The statement two parallelograms are similar is always never or sometimes true?

Are two obtuse triangles sometimes always or never similar?

Are a scalene triangle and an isoceles triangles sometimes always or never similar?

Are Two isosceles triangles are sometimes always or never similar to each other?
Sometimes.
Is these two triangles always congruent sometimes congruent or never congruent?
Never
Is an altitude always sometimes or never an angle bisector?
sometimes, the altitude of isosceles triangles resting on their base and equilateral triangles are angle bisectors
Are two equilateral triangles sometimes always or never similar to each other?
Since triangles have three sides and must have interior angles equal to pi or 180o, the three interior angles in all equilateral triangles will be pi/3 or 60o.However, equilateral triangles must also have equal side lengths. Since equilateral triangles with interior angles of 60o will not necessarily have the same side lengths, two equilateral triangles will sometimes be similar to each other.
Are two hexagons always sometimes or never similar?
sometimes
Is an isosceles and a scalene triangle always sometimes or never similar?

Is two squares always sometimes or never similar?

Is two regular polygons always sometimes or never similar?
