## What are the steps to prove the Pythagorean Theorem?

½(a2 + 2ab + b2) = ab + ½c2.

- ½(a2 + 2ab + b2) = ab + ½c2.
- Multiply both sides by 2 to get rid of the ½: (a2 + 2ab + b2) = 2ab + c2.
- Subtract out the 2ab: a2 + b2 = c2.
- You’re left with the proof: a2 + b2 = c2.

## How do you make a Pythagorean Theorem project?

Pythagoras Theorem and its Extension

- Cut a triangle of sides 6cm, 8cm and 10cm.
- Cut squares equal to sides of triangle.
- Divided each square into small squares of 1cm each.
- Took right circular cylinders of radii 6cm, 8cm and 10cm.
- Filled the two smaller cylinders (r = 6cm, 8cm) with sand.

**What is paper cutting and pasting method?**

Draw a circle of any radius on a sheet of paper (Take r = 6.5 cm) using compass. Fold it once along the diameter to obtain two semicircles as shown in fig. (ii). Again fold the semicircle to get quarters of circle. Repeat this process of folding upto four folds and then it looks like a small sector as shown in fig.

### What is cutting and pasting method?

Cut and paste are two commands that are commonly used together in computer user interface interaction and provide a method of transferring data from one location to another. Unlike the copy and paste commands, which create a duplicate in the new location, cut and paste moves the entire contents to the new location.

### What are the three formulas of Pythagoras Theorem?

The Formula of Pythagorean Theorem

- Hypotenuse^{2} = Perpendicular^{2} + Base^{2}
- Area_{total} = Area_{four \ triangles} + Area_{small `\ square}\\
- (a + b)^2 = 4 \times ( \frac{1}{2} a \times b ) + c^2 \\
- a^2 + 2 a \times b + b^2 = 2 a \times b + c^2\\
- a^2 + b^2 = c^2\\
- Hypotenuse^{2} = Perpendicular^{2} + Base^{2}

**What are the three formulas of Pythagoras theorem?**

#### Who is the father of Pythagoras theorem?

Pythagoras of Samos ( Greek: Πυθαγόρας; circa 582 BC – circa 507 BC) was an Ionian ( Greek) mathematician and philosopher, founder of the mathematical, mystic, religious, and scientific society called Pythagoreans. He is best known for the Pythagorean theorem which bears his name.

#### Is a 2 B 2 C 2 only for right triangles?

Pythagorean theorem: If a triangle is a right triangle (has a right angle), then a2+b2=c2. Converse: If a2+b2=c2 in a triangle with c is the longest side, then a triangle is a right triangle. Obtuse: Has a single obtuse (greater than 90 degree) angle and 2 acute angles.

**What is Pythagoras theorem BYJU’s?**

Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named as Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°.
