4. An angle is created where two lines intersect. Angles that make up a line (add up to 180 degrees) are called supplementary angles. Angles that make up a right angle are called complementary angles. Angles that are across from each other are called vertical angles. When two parallel lines are intersected by a third line (called a transversal) the corresponding acute angles are congruent and the corresponding obtuse angles are congruent. Angles that measure less than 90 degrees are called acute angles. Angles that measure more than 90 degrees are called obtuse angles. SAT MATH ROUND 3 PART 2

7. A triangle with two equal sides and two corresponding equal angles is called an Isosceles Triangle. A triangle with no equal sides and no equal angles is called a Scalene Triangle. A triangle with three equal sides and three corresponding equal angles is called a regular/equilateral triangle. Each angle equals 60 degrees. A triangle with one right (90 degree) angle is called a Right Triangle. SAT MATH ROUND 3 PART 2

8. Triangle Inequality Theorem: Every side of triangle must be longer than the difference of the lengths of the two other sides and shorter than the sum of the lengths of the two other sides. Similar Triangles have equal angles and proportional sides. SAT MATH ROUND 3 PART 2

9. A Pythagorean Triple is any combination of 3 lengths of a triangle’s sides that, when taken together, always satisfy the Pythagorean Theorem. The three most commonly tested Pythagorean Triples (in order) are: 3-4-5 5-12-13 8-15-17 Know their multiples as well. SAT MATH ROUND 3 PART 2
