GRE Math Strategies

Subjects : gre, math
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. In a triangle - if ?c(interior angle in triangle) and ?d(exterior angle out of triangle) are supplmentary angles - than ?a and ?b are remote interior angles to <d - thus - a +b+c = 180 (triangle) c+d = 180 (supplementary angles)
