Question

two consective angel of a parallelogram are in the ratho 1:3 then what will be the smaller angel​

Answer 1

Answer:

45°

Step-by-step explanation:

We know that sum of 2 consecutive angles in a parallelogram is 180° due to co - interior angle property in parallel lines.

Now, ratio = 1:3

Thus, let the angles be x and 3x.

Acc. to co - interior angles property,

x + 3x = 180°

=> 4x = 180°

∴ x = 180°/4 => 45°

As x was the smaller angle between x and 3x, the smaller angle is 45°.
