Yes.
If u have to prove it then read below:
A circle with centre O of diameter AB and a point on circle by arc subtended by semicircle is C.
According to therem;
Angle subtended by an arc at centre is double of angle at circle.
Since AB is diameter.Means Angle AOB = 180°.
Since Angle AOB = 2 * Angle ACB
=) 180° = 2* Angle ACB
=) 180°/2 = 90°= Angle ACB.
Hope it's helpful to u.
