Seesaw bond angles

How many bond angles in a seesaw-shaped structure are 90 degrees wide? I know the structure has both 90 and 120 degree angles but I'm not sure of how many of each are there.

There are two 90 degree lone-pair-bonding-pair repulsions, but I am not sure about the number of 120 degree bond angles.

I believe there would be two <120 degree angles. The angle between the lone pair and each of the two bonding pairs that lie on the same plane as that lone pair is <120 degrees.

The seesaw shaped structure resembles an actual seesaw. There are two 90 degree bond angles (the angle with the part where the people sit and the legs) and then there is a <120 degree angle(the angle between the legs of the seesaw). The angle between the lone pair and the two bonding pairs is greater than 120 degrees.
