Copy and past the following link in a new tab in your browser. Click on the question mark and investigate using the tool. Upload a screen shot of your tiling pattern in the show your work area.

Consider the angles inside a single parallelogram from the pattern.  Which angles are congruent?  How can you justify your claim (perhaps using the tiling pattern you created)?

Mark all other angles that are the same as the green with another green mark. Do the same with the purple.

Watch my video about this great investigation! Then mark the angles that are congruent in the picture below.

Are the corresponding angles always congruent? There are two pictures below. Which picture has corresponding angles that are congruent and which one doesnt (135 and x are corresponding. Ignore the y for now)? Why do you think the one picture's angles are not congruent?- USE WORDS to explain.

If the measure of angle 3 is 130 degrees, what is the measure of angle 7? Why?

Looking back-If angle 5 is 120 degrees, what is the measure of angle 6? Why- meaning- what kind of angles are they?

Looking back-If the measure of angle 2 is 48 degrees, what is the measure of angle 4? Why- meaning- what kind of angles are they?
