Reflections across a line with angle measures
Click and drag H or G to change the line of reflection. Select any point of the preimage to change the shape. Checking the ''Line Segments'' box will show line segments between the points on the preimage and the points of the image. Checking the ''Distances'' box will show the distances from each point to the line of reflection. Checking the ''Angle Measure'' box will show the angle measure between the line of reflection and the line segments connecting the corresponding vertices of the preimage and the image.
