What are the Angles and Lengths of the Sides?

Can you find the size of each angle?

Can you find the size of each angle and size of each side?

This pattern when made with the pattern blocks doesn't seem to fit together very precisely.

Is this because the blocks aren't made for these shapes to fit precisely?or

Were they are made precisely and the person that created the pattern was sloppy and

didn't fit the blocks together?

Hints:

Label all the angles and see if there is a logical solution.
