Question 1

3 m 60 cm = 3.06 m

Answer 1

Yes, this statement is true. ✔️

Explanation

When we write the table for measurments, we see that Metre is in between (refer attached sheet).

• 1m = 1/100 cm or
• 1m = 1.0100 m

So, we have got the direct answer (attached sheet 2).

Question 2

The three line segments forming a triangle are called the vertices of the triangle.

Answer 2

Yes, this statement is false. ✖️

Explanation

• Three line segments make up a triangle. This statement is correct.
• Here, vertices is plural form of vertex.

Question 3

A line has a definite length.

Answer 3

No, this statement is false. ✖️

Explanation

• A line has no definite lenght.
• A line segment has a definite lenght.
• A line exceeds infinitely without stopping.

If you are confused whether a lone is line or a line segment, follow these steps.

• If a line is a line, then it will be a single line i.e. ----------.
• If a line is a line segment, it should always include <-------> kind of symbol for line.

Answer 2

Required Answers :

State true of false and write correct statements for the false ones.

1. 3 m 60 cm = 3.06 m

Answer - The above statement is True. Let's verify our answer once.

As we know that,

1 m = 100 cm

So, 60 cm = ( 60 ÷ 100 ) 0.6

Now, let's combine both the units, therefore our final answer is 3.06 m

Hence, Verified!

2. The three line segments forming a triangle are called the vertices of the triangle.

Answer - The above statement is False. The correct statement is, The three line segments forming a triangle are called the arms of the triangle. Now, let's understand why?

Vertices is the plural form of Vertex and the common point of two rays or line segments is called vertex of the triangle.

3. A line has a definite length.

Answer - The above statement is False. The correct statement is, A line has an indefinite length. Now, let's understand why?

A line is a collection of points extended endlessly ( indefinitely ) in both the directions along a straight path. A line has no beginning no end. It has no end points.

• When the word line is used, it means a straight line.

• A line is represented as a double arrow that it can be extended without limit in both directions.

• ↔️ is the symbol of a straight line

• To name a line, any two points on the line are chosen and named by Capital Letters of the English Alphabet
