Creating a Concept Study Guide
Date_____________________________
Directions: When we come back from break we will have a test to close our study of triangles
before studying special segments of triangles. For this test, you will be allowed to use a study
guide that you will compose the next two class periods. Here are some ideas of what to include:
1. Important vocab: acute, right, obtuse, right, scalene, legs, base, etc.
2. How do you know if three side lengths make a triangle? (Triangle Inequality Theorem)
a. Draw a picture and explain when three sides would not make a triangle.
3. How do you know if three side lengths make an acute, right or obtuse triangle?
4. Given two sides can you find the interval the third length must fall between?
5. Given just a triangles angle measurements, how can we classify that based on its sides?
a. How do side lengths and angles relate?
6. Interior and exterior angles of a triangle and their measure.
7. What is the Pythagorean Theorem?
8. How do you classify a triangle given three points on the Cartesian Plane?
9. What is a Pythagorean Triple?
a. What are two examples of a Pythagorean Triple?
10. What does the Isosceles Triangle Theorem tell us?
11. What are the two types of bisectors do we have and what do they tell us?
12. How to write and use congruency statements.
13. Describe your thought process when doing proofs.
a. What do you do first? Last?
b. If your “prove statement” is to prove two triangles are congruent, what must your
last reason of the proof must be?
14. When do we want to use CPCTC?
15. Any important information you use when doing proofs (difference between a segment
bisector and an angle bisector, the reflexive property).
