[b]Lines a and b are intersecting lines, forming two types of angle pairs: Vertical Angles and Linear Pairs.[/b] [color=#c51414][b]Move one slider at a time.[/b][/color] [b][color=#1551b5]Drag around the points to change the measures of the angles.[/color][/b] Which type of angle pairs are always congruent?: Which type of angle pairs are always supplementary (add to 180): Which type of angle pairs are Adjacent Angles? What do all the angles add up to? Write your answers on the Google Doc attached to this assignment.
Points A, B, C, and D can be moved by the user to change the orientation of the intersecting lines. Point E must be the center of the circle for the demonstration to work.
