Question

Locate square root of 2 on the real number line​

Answer 1

Answer:

I am sending you a picture

Step-by-step explanation:

1. draw a number line.

2. draw 2 perpendicular lines from 0 & 1.

3. draw arcs with centers 0 and 1 respectively to the perpendiculars such that they intersects on the perpendiculars with radius of distance from 0 to 1

4. now join the intersection points and name them as A and B.

5. now join 0B and draw an arc with center 0 and radius 0B to the number line.

6. the intersection point is the root of 2.

Answer 2

Answer:

1. Firstly let's take a number line.
2. Let 0 be O and 1 be A. OA be the base.
3. Let A - B be the height with 1 unit.
4. AB perpendicular to AO.
5. Let's join O and B.

Therefore, now both AB, OB are equal to 1 unit.

Now using Pythagorean theorem:

⇢ OB² = OA² + AB²

⇢ 1² + 1²

⇢ 2

Now, taking square roots on both the sides:

⇢ OB = √2

Now, here OB is equal to √2 but we need this √2 here on number line.

So, now it's time to take the geometric equipments.

1. Take the vertex point on point O.
2. Now cut an arc in OB on the number.
3. The new point on the number like would be C.
4. Taking the arc we can replace the measure of OB to OC on the number line.

Therefore, OC = √2.

• You can draw these measures using the above steps
