Concept explainers

Percentage

A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

Subtraction

Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.

Addition

Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.

Question

Chapter 1.3, Problem 4CE

To determine

To find: If two different names of rays, represent the same ray.

Expert Solution & Answer

Answer to Problem 4CE

No. AB→ is not the same as BA→ .

Explanation of Solution

Given information: Consider the figure shown.

McDougal Littell Jurgensen Geometry: Student Edition Geometry, Chapter 1.3, Problem 4CE

Concept used: A ray always has an initial point but no end point. It is represented by one headed arrow. Thus, a ray AB→ consists of the line segment AB¯ and another point C, such that B is between A and C.

Calculation: So, in ray AB→ , A is the initial point and its direction is towards B, but in ray BA→ , B is the initial point and its direction is towards A.

Conclusion: As AB→ and BA→ represent two different rays, AB→ is not the same as BA→ .
