B Similar figures always have the same size.

D Similar figures always have corresponding sides that are proportional.
how to solve it
The sum of the interior angles of a polygon is 1440°. Find the number of sides of the polygon.
Can you please clarify the answer
If a polygon has 'n' sides, then it is divided into (n – 2) triangles. The sum of the angles of a triangle = 180°. Therefore, the sum of interior angles of a polygon having n sides is (n – 2) x 180.
(n - 2) x180 = 1440
n - 2 = 1440/180 = 8
n = 8 + 2 = 10
