It's impossible for a quadrilateral to have no equal sides and have right angles.
A rhombus has 4 equal sides but no right angles whereas a square has 4 equal sides and 4 right angles.
An obtuse triangle can have no right angles, and has two equal angles.
Such a shape is called a rhombus.
That is called a rhombus
supplementaryA:Two angles whose sum measures a right angle are complementary angles.
It's called a rhombus.
A rhombus has 4 right angles just like the square * * * * * In general a rhombus has a pair of equal obtuse angles and a pair of equal acute angles. It is only in a special case that the shape has 4 right angles and then it is called a square.
A right triangle can have 2 equal angles if they are each 45° (any other right triangle will have no equal angles)
