A four sided polygon, 4 edges and 4 corners
Answer:
Consecutive sides must be congruent.
All interior angle adds up to 360°
Step-by-step explanation:
Rhombus:
1. Sides: all 4 sides are congruent.
Then consecutive sides must be congruent.
2.Diagonals : Diagonals bisect each other at 90°.
So, second option is wrong.
3. Sum of interior angle is 360°.
Answer:
Sam is incorrect.
Step-by-step explanation:
Using Pythagorean Theorem, we can find the length of diagonal SQ as 13.4 (6^2 + 12^2 = c^2, 36 + 144 = c^2, sqrt(180) = c, c is approx 13.4). We can do the same for diagonal OM (6^2 + 6^2 = c^2, 36 + 36 = c^2, 72 = c^2, sqrt(72) = c, c is approx 8.5). Sam is therefore incorrect because 13.4 is not double of 8.5.
