1980°

152.3°

3780°

164.35°

180°

360°

Step-by-step explanation:

The sum of all the interior angles of a polygon is given by (n - 2) 180° where n is the number of sides.

So, the sum of all interior angles of a 13-gon is (13 - 2) 180° = 1980° (Answer)

As the 13-gon is regular, so each angles will be same. Assume each angle is x°.

So, 13x = 1980, ⇒ x = 152.3° (Answer)

Now, the sum of all interior angles for a 23-gon will be (23 - 2) 180° = 3780° (Answer)

Again, as the 23-gon is regular, so each angles will be same. Assume each angle is x°.

So, 23x = 3780, ⇒ x = 164.35° (Answer)

The sum of all the interior angles of a triangle is 180° (Answer)

The sum of all the interior angles of a quadrilateral is 360° (Answer)

The similarity between a square and a rhombus is all the sides of both are same and the difference, between a square and a rhombus is that a square has every angle 90°, but the rhombus has no angle equal to 90°. (Answer)
