To prove the transitive property, we will assume that a, b, and c are real numbers and that a = b and b = c, then we will show that a = c. Since we have that a = b, the _____ property gives that b = a. You can think of the word reflexive and think about reflections. Hence, a relation is reflexive if: Education. Solution: Reflexive property: Assume that x belongs to R, and, x – x = 0 which is an integer. Geometric figures, line segments, angles, and geometric shapes can all show congruence.

Again, it states simply that any value or number is equal to itself. Did you know… We have over 220 college lessons in math, English, science, history, and more. For any numbers a and b , if a = b then then b = a B. If we want our numbers to match, they have to be the same. a) Reflexive property b) Symmetric property, The reflexive property of equality says: (choose the correct option) A. Since b = a, we can plug a into the equation b = b for b on the left-hand side of the equation, and since b = c, we can plug c into the equation for b on the right-hand side of the equation.

This proves the symmetric property that if a = b, then b = _____. And x – y is an integer. This property tells us that anything is equal to itself. Enrolling in a course lets you earn progress by passing quizzes and exams. Symmetric Property of Equality If a = b, then b = a . 2x + y = 2x + y. Reflexive Property Definition : The reflexive property of equality simply states that a value is equal to itself. Transitive Property of Equality If a = b and b = c, then a = c. Reflexive Property of Equality a = a . Try refreshing the page, or contact customer support. 4.789 = 4.789 . The term reflexive is a good example. Answer is B Properties of Equality Let a, b, and c be real numbers. If we really think about it, a relation defined upon “is equal to” on the set of real numbers is a reflexive relation example since every real number comes out equal to itself. credit-by-exam regardless of age or education level. Get the unbiased info you need to find the right school. With the Reflexive Property, the shared side or angle becomes a pair of congruent sides or angles that you can use as one of the three pairs of congruent things that you need to prove the triangles congruent.
