Rectangle A has length 12 units and width 8 units. Rectangle B has length 15 units and width 10 units. Rectangle C has length 30 units and width 15 units.
Here are 3 polygons.
Draw a scaled copy of Polygon A with scale factor \(\frac 1 2\).
Draw a scaled copy of Polygon B with scale factor 2.
Draw a scaled copy of Polygon C with scale factor \(\frac 1 4\).
Lines \(AB\) and \(CD\) are parallel. Find the measures of the following angles. Explain your reasoning.
Three lines in a plane. Line A B. Line B F. Line D E. Lines B F and A B intersect at the point B. Lines B F and D E intersect at point C. Line D E is above line A B. Angle A B F is labeled 38 degrees.
