will the bond strength affect the bond angle in a molecule? do molecules like CF4 and CF2Cl2 have the same bond angle? if not how are the bond angles changed?

Bond angles shouldn't be affected by differing bond strength. For example, a double bond between two atoms is stronger than a single bond, but this won't matter in regards to bond angles and shape. Hope this helps!

Since single, double, and triple bonds are all just considered one region of electron density (for the VSEPR model), they do not differ in bond angles; as long as the shape remains the same, so should the angle.

Since all bonds are treated equivalently, they type of bond (whether its a single, double, triple) wouldn't affect its shape.

As mentioned previously, bond length will have no effect on bond angle rather it's the types of bond present that affect shape and angle. As a rule of thumb, repulsion strength follows as Lone lone pair > lone bonding pair > bonding bonding pair, with the greater the repulsion strength giving the greater the angle.
