Question

is 45° supplement of 45°​

Answer 1

No!

How?

• 45° is not a supplement of 45° because these angles add upto 90°.
• Supplementary angles add upto 180°.

Answer 2

As we know that,

Supplementary angles are those two angles whose value when added will equals to 180 degree.

As per question,

The value of the angle is 45 degree.

So, for determining the value of supplementary angle we will subtract the value of angle from 180 degree.

Thus the value of supplementary angle of 45 degree will be,

$=180^0-45^0=135^0$

Hence, value of supplementary angle of 45 degree will be 135 degree.

So, the above statement,

is 45° supplement of 45°​ is completely false.
