An isosceles or equilateral triangle,
An isosceles trapezium, a paralleolgram, a kite, a n arrowhead.
Any polygon with more than 4 sides can have two (or more) of them being congruent.
two polygons with sides that have all equal sides and angles
They are called regular polygons
To be considered similar, two polygons must have corresponding angles that are equal, and their corresponding sides must be in proportion, rather than equal. This means that while the shapes of the polygons are the same, their sizes may differ. Thus, similar polygons maintain the same shape but can vary in scale.
A parallelogram, or a range of polygons with 6 or more sides which can have sides with the required qualities.
Yes.
two polygons with sides that have all equal sides and angles
Yes, the corresponding sides of two similar regular polygons must have equal lengths. This is because both the polygons are similar, which means that since they are also polygons, they must have equal lengths.
If two polygons are similar then the ratio of their perimeter is equal to the ratios of their corresponding sides lenghts?
Yes, regular polygons will have all sides equal length, and all angles the same. If two polygons of the same number of sides are 'regular' then those two polygons will be similar (they may be scaled, for example).
no. only regular polygons do
They are called regular polygons
Regular polygons have all sides equal in length but an irregular polygon does not have all sides equal.
This is False.
A kite, or selected polygons with 5 or more sides.
regular polygons are the ones that all sides are equal
To be considered similar, two polygons must have corresponding angles that are equal, and their corresponding sides must be in proportion, rather than equal. This means that while the shapes of the polygons are the same, their sizes may differ. Thus, similar polygons maintain the same shape but can vary in scale.
A parallelogram, or variants of polygons with 6 or more sides.
