The shape that has not got equal side is a rectangle
it has to have equal angles, not side lengths. otherwise it would just be two of the same shape
Pentagon ,,,, 180 digr
The answer depends on what shape the question is about.
An isosceles triangle is one of them
An isosceles triangle has two equal sides and one different side.
regular pentagon maybe maybe not
An EQUILATERAL TRIANGLE
Isoceles Triangle
If all side lengths are changed so the new shape is proportionately equal, the angles don't change. But if it's not proportion. equal, then the angles will be different
If a shape has equal angles and side lengths then it is known as a regular polygon
It is a square or a rhombus of which both have 4 equal side lengths.
