Each pair of shapes is congruent. Identify a transformation or sequence of transformations that could take one shape to the other.
Here is a line m and a point C not on the line. Use straightedge and compass tools to construct a line perpendicular m to line that goes through point C.
How do you know the line you constructed is perpendicular to line m?
Here is a line m and a point C not on the line. Use straightedge and compass tools to construct a line parallel m to line that goes through point C.
