Warm up dealt with writing congruence statements from two triangles with limited information. Passed out standards guide and project information. Project information and sample project linked below.

Warm up on rigid motion congruence. Went over homework, then examined triangle congruence criteria.
Handout from class
Task 2:
READ ME FIRST
As we saw in class, you don't always need all 12 pieces of information to show that two triangles are the same. Rather, you can take a 'shortcut' and determine congruence with only 3 pairs of information rather than 6 pairs.
Click the options in the corner of the applet below so that Side-Side-Side appears in the top of the screen (this corresponds to SSS in your table). See if this always results in congruent shapes. Then try options until Side-Angle-Side (order matters) appears at the top, and work your way down the table.
If the applet below doesn't work, try this: LINK

TASK 4: ONLINE PRACTICE (record your progress on your handout; do your work in your notebook)
TASK 5: this was not working earlier. if it doesn't let you sign on, then just watch the hw videos below.
TEXTBOOK PRACTICE: (see instructions on your handout, record progress there too)
Warm up on matching triangle congruence criteria figures with the appropriate shortcut. Examined triangle rigidity and its application in architecture and engineering, then made a foldable resource with examples of each criterion. Applied these in cases where triangles shared a side, then did our first two-column proof example involving overlapping triangles.
