Welcome back! Send me you answers! If you have not started these problems yet, go back to #1 on yesterday’s post and get started. Keep a notebook with all of your problems worked out.
5. If a=b and b=c, than a=c illustrates which property?

a. Is the triangle isosceles, equilateral, or scalene?
b. What is the measure of the 3rd angle?
c. Is the triangle right, acute, or obtuse?
