Mathematics is the study of numbers, shapes, quantities, and patterns. Mathematics is the ‘queen of all sciences’ and its presence is there in all the subjects. It acts as the basis and structure of other subjects. Some points to remember:

  • On the basis of intuition, hypothesis are made in mathematics.
  • A mathematics statement can be conditional. For example, a figure can not be said a 'rectangle' its opposite sides are not parallel and equal, and all angles are inclined at 90 degrees.
  • Mathematics is not about theorems only. It contains other symbols, statements like axioms, and calculation.
  • A person with good arithmetic computation does not guarantees that he is good in mathematics. Maybe he can lack in geometry or algebra.

Hence, a mathematics statement can be conditional.

Hint: There are four statements given. We will draw figures for each statement and then we will write arguments against the incorrect statements and in support of the right statement. Finally, we will be able to find the statement which is true.

Complete step by step solution:
We have been given four statements and we have to find the correct one. We find the right argument involving each statement and also draw their respective diagrams to find the conclusion.
We know that an infinite number of lines can pass through one single point. These lines have one common point.

Which of the following statements is true math


For the above line we can see that the lines are intersecting themselves at a single point A.
So, the first statement is wrong.
We know that two distinct points are required to get a particular line. This means there can be only one line going through two distinct points.

Which of the following statements is true math


We can see that there exists only one line that goes through the points C and D. The second statement is wrong.
The fourth statement is also wrong as two circles with equal radii are called equal circles. Therefore, if two circles are equal, then their radii are equal.

Which of the following statements is true math


For the above diagram the radii are equal which means $AB=CD$. They are equal circles.
If two lines have more than one common point then that means they are intersecting each other at more than one point. We know that two distinct points are required to get a particular line. This means there can be only one line going through two distinct points.

Which of the following statements is true math


The third statement is right.
So, the correct answer is “Option C”.

Note: Equal circles are those whose diameters are equal, or whose radii are equal. They also can overlap each other. Two lines are distinct if they intersect at one and only one point or if they are parallel, that is there is no point of intersection between them. ... Any two adjacent sides of a triangle are also distinct lines.

What is a true statement in math?

A true statement is one that is correct, either in all cases or at least in the sample case. For example, the number three is always equal to three. It's also equal to six divided by two. Any variable, like x, is always equal to itself.

Which are statement are true?

A statement is true if what it asserts is the case, and it is false if what it asserts is not the case. For instance, the statement “The trains are always late” is only true if what it describes is the case, i.e., if it is actually the case that the trains are always late.

What mathematical statements must be proven to be true?

In mathematics, a theorem is a statement that has been proved, or can be proved. The proof of a theorem is a logical argument that uses the inference rules of a deductive system to establish that the theorem is a logical consequence of the axioms and previously proved theorems.

Which mathematical equation is true?

To make a true equation, check your math to make sure that the values on each side of the equals sign are the same. Ensure that the numerical values on both sides of the "=" sign are the same to make a true equation. For example, 9 = 9 is a true equation. 5 + 4 = 9 is a true equation.
