SUMMARY
An equilateral pentagon cannot have four right angles in spherical geometry due to the properties of Lambert quadrilaterals. In spherical geometry, the sum of the angles in a polygon exceeds the Euclidean limit, requiring that each angle in a pentagon be greater than 108 degrees. Consequently, it is impossible to have four angles of 90 degrees in such a configuration, as this would violate the fundamental principles of spherical geometry.
