Answer 1

Answer:

Square is the odd one with all angles of 90 degree and all others have either less than or more than 90 degree angles between two sides.

Step-by-step explanation:

Equilateral Triangle= All sides are equal and all angles are less than 90 degree. Sum of angles =180 degree and 3 sides

Square= All sides are equal and angles are 90 degree. sum of angles= 360 degree and 4 sides

Regular pentagon= All sides are equal and angles are more than 90 degree. sum of angles= 540 degree and 5 sides

Regular Hexagon= All sides are equal and angles are n=more than 90 degree. sum of angles= 720 degree and 6 sides
