The ratio of total interior angles to total exterior angles of a quadrilateral is Select one:
a. 3:1
b. 1:2
c. 1:1
d. 2:1

9514 1404 393

  c.  1 : 1

Step-by-step explanation:

The total of exterior angles of any convex polygon is 360°. The total of interior angles of a quadrilateral is 360°. So, the ratio of interest is ...

  interior : exterior = 360° : 360° = 1 : 1

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
