Answer:
None of the statements is true for all the three angles at the same time
Explanations:
Note:
Sum of angles in a triangle = 180 degrees
Sum of angles on a straight line = 180 degrees
In the first triangle:
a + b + y = 180 (Sum of
x + y = 180 (Sum of
x = a + b (Sum of two opposite interior
For the second triangle:
a + b + x = 180 (Sum of
x + y = 180 (Sum of
y = a + b (Sum of two opposite interior
For the third triangle:
a + b + x = 180 (Sum of
x + y = 180 (Sum of
y = a + b (Sum of two opposite interior
