If tan A = 1, we can use the relationship between tangent and sine in a right-angled triangle.
an A = 1, we can use the relationship between tangent and sine in a right-angled triangle. In a right triangle, tan A is the ratio of the length of the side opposite angle A to the length of the adjacent side. If tan A = 1, it means the side opposite A is equal in length to the adjacent side.
Now, considering this right triangle, the ratio of the length of the side opposite angle A to the hypotenuse is sin A. Since the side opposite A is equal to the adjacent side in this case, the ratio of sin A is 1.

:. Therefore, if tan A = 1,
then sin A = 1.
