rectangle
A rhombus, I believe.
It is an isosceles triangle when two of its three sides are of the same length.
If only two sides of a triangle are the same length it is an isosceles triangle. If all three sides are the same length it is an equilateral triangle.
An isosceles triangle has two sides of the same length.
A kite or arrowhead.
Hexagons have six sides, not four. Any number of them can be of the same length.
Not necessarily, but the two non parallel sides could be the same length.
A polygon with two equal sides!
An isosceles triangle has two sides the same length. An equilateral has all 3 sides the same length. A scalene triangle doesn't have any sides that are the same length.
isosceles triangle has two sides equal in length and two angles of the same measure;
No because then it would be an isosceles triangle. Scalene triangles have no sides of the same length. Isosceles have two sides of the same length and equilateral has all side of an equal length.
