Now you are going to take an interactive assessment and a module practice test that will help you understand how prepared you are to take the module test. Complete the interactive assessment below, and then complete the module practice test.

Take your time and try your best. You will receive feedback on the both assessments automatically and should review anything you missed. If you still have questions about any of the material, go back and review the lessons and feel free to contact your instructor!

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
