How can we find the measure of an exterior angle if we know the measurement of an interior angle

Determine the relationship of ab and cd given the following points

First work with stencil one. use a combination of reflections, rotations, and translations to see whether stencil one will overlap with the original pattern. list the sequence of rigid transformations you used in your attempt, noting the type of transformation, the direction, the coordinates, and the displacement in
