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.

Chapter 3.1, Problem 1PSA
To determine

To calculate : The congruent triangle for ERC is to be calculated

Expert Solution & Answer
Check Mark

Answer to Problem 1PSA

The congruent triangle for ERC is ΔTCR

Explanation of Solution

Given information : The following information has been given

  ∠REC≅∠CTR

  RE→≅CT→

  CE→≅RT→

Formula used : If two triangles have two congruent sides, and the angle between them is also congruent, then the triangles are also said to be congruent by SAS property

Calculation : Comparing the triangles ERC and TCR for thee information

  ∠REC≅∠CTR

  RE→≅CT→

  CE→≅RT→

We can say that they are congruent by SAS property mentioned above

Hence,

  ΔERC≅ΔTCR
