Explanation

A circle does not have a side and hence no vertex.

Hence, "circle" is different from all other given shapes.

The square has 4 sides,

A hexagon has 6 sides,

triangle has 3 sides. 

Explanation

90 percent *90

= (90/100)*90

= (90*90)/100

= 8100/100

= 81

Explanation

 The sum of all interior angles in any triangle is always 180 degrees

A fundamental rule in Euclidean geometry, regardless of the triangle's shape (e.g., right, equilateral, scalene).

This property is known as the Angle Sum Property. 

Explanation

A+B = 60

B+C = 64

C+A = 68

Add 'em up:

2(A+B+C) = 192

A+B+C = 96

C = (A+B+C) - (A+B)

= 96 - 60

= 36
