Question

A rectangle is a parallelogram with equal angles. What is the full meaning of the definition?

Answer 1

Hye mate,

Here is your brilliant answer.

Euclidean plane geometry, a rectangle is a quadrilateral with four right angles. It can also be defined as an equiangular quadrilateral, since equiangular means that all of its angles are equal (360°/4 = 90°). It can also be defined as a parallelogram containing a right angle.
