Answer:
regular polygon of 9 sides has 9 lines of symmetry
Answer:
-15626
you just multiply -5 by itself 6 times
Step-by-step explanation:
The Pythagorean theorem is the idea that the sum of the two legs which are both squared is equal to the hypotenuse's length squared.
*<em>look at the image I attached for a better explanation</em>
By looking at the picture, we are missing the leg's length, and by using the Pythagorean theorem, we get the equation
![?^2+5^2 = 13^2\\?^2 + 25 = 169\\?^2 = 144\\? = 12](https://tex.z-dn.net/?f=%3F%5E2%2B5%5E2%20%3D%2013%5E2%5C%5C%3F%5E2%20%2B%2025%20%3D%20169%5C%5C%3F%5E2%20%3D%20144%5C%5C%3F%20%3D%2012)
Thus the <u>missing side length is 12 cm</u>
Hope that helps!
If a quadrilateral has exactly 2 lines of symmetry and both are angle bisectors then the figure must be a rhombus because it has exactly 2 pairs of congruent angles.
I hope this helps! :)
