Step-by-step explanation:
the area of a square is the length multiplied the breadth
in a square, all sides are equal so:
A=n×n
A=n²
This is usually used as a proof that triangles have 180°. Look at the attached figures. If you cut off angle A, angle B and angle C and rotate them so that their vertices touch, you form a half-circle out of them (or a straight line). We know that half a circle is 1/2 of 360° or 180; therefore all 3 angles in a triangle must add up to 180°.
False, they are both quadrilaterals though.
