OH NO! I lost my math notes! My test is tomorrow!
AAAAAAH!!!! A ghost!
Fear not, young mortal. I am the math ghost. I will not rest until you understand the math required of you.
The test is about classifying triangles. Do you think you could help me with that?
Of course I can. Follow me to my old classroom.
This is an equilateral triangle. Is it classified this way because all the side are the same length.
This is a right triangle. It is classified this way because one of the angles is exactly 90 degrees, or a right angle.
This is an isosceles triangle. It is classified this way because it has two congruent sides, and one side that is not congruent. I remember this through a little trick: That poor, single side is saying, "I'm so lonely!"
Thank you, Math Ghost!!! I'll ACE the test for sure now!
You are very welcome. now go! you will be late if you do not hurry!
