In a triangle you have 3 angles that add up to 180°. So an equilateral triangle would each have angles of 60°.
In a square you have 4 angles that add up to 360°. So a square would each have angles of 90°.
The pattern continues for other regular polygons:
Pentagon - 5 angles add to 540° (360° + 180°) so each angle is 108°.
Hexagon - 6 angles add to 720° (540° + 180°) so each angle is 120°, etc.
Interior angles:
Equilateral triangle --> 60°
Square --> 90°
Pentagon --> 108°
Hexagon --> 120°
Septagon --> 900°/7 = 128.57°
etc.
The answer for a square is 90°.

We know that each corner of a square is 90 degres.
Because the sum of these 4 corners is 360 degres( 4 X 90 degres). So an interior angle of a square is 90 degres.
Final answer: 90 degres
