Question

I which of the following canbe four interior angles of aquadrilateral? 1)140 degrees, 40 degrees, 20 degrees, 160 degrees. 2)260 degrees, 150 degrees, 30 degrees, 20 degrees; 3)40 degrees, 70 degrees, 90 degrees, 60 degrees; 4)110degrees, 50 degrees, 30 degrees, 180 degrees;
​

Answer 1

Answer:

1) 140°, 40°, 20°, 160°

Step-by-step explanation:

We know that sum of interior angles of quadrilaterals is 360 degrees.

So, 140 degrees + 40 degrees + 20 degrees + 160 degrees = 360 degrees

In option (d) has an angle sum equal to 360 degrees, but one angle is 180 degrees if it is considered then the quadrilateral becomes a triangle.
