Question

YO VERIFY THAT THE SUM PF 4 ANGLES OF A QUARDILATERAL IS 360 DEGREE


Measures of ∠A = ………. ,
∠B = ………. ,
∠C = ………. ,
∠D = ………. ,
Sum of  ∠A + ∠B + ∠C + ∠D = ………. .​

Answer 1

Answer:

for verifing it , take a quadrilateral draw a diagonal line cutting it half , then we see that they form two triangles and as we know that sum of angles in a triangle is 180 degrees so 180+180 is 360 degrees . hence proved.
