A trigonal planar molecule such as sulfur trioxide (SO3) or boron trihydride (BH3) has a trigonal planar shape.
Trigonal pyramidal molecules such as ammonia (NH3) have bond angle closer to 107 degrees.

No, the bond angle for linear structure is 180 degrees.
Trigonal Planar (120 degrees)
120 degrees
Trigonal Planar. The ideal angle between the carbon and oxygen bond is 120 degrees
A 120-degree angle is an obtuse angle, meaning it is greater than 90 degrees but less than 180 degrees. It is formed when two lines intersect and the angle between them measures 120 degrees. In a triangle, a 120-degree angle would typically be found at one of the vertices.
