Pythagorean Theorem and Applications

This video tutorial covers the Pythagoras theorem, explaining how to find the hypotenuse and shorter sides of right triangles, calculate diagonals in 2D objects, and apply the theorem to 3D objects. It provides step-by-step instructions and examples to help understand the concepts and solve related problems.

What is the Pythagoras Theorem primarily used for?

• Determining the volume of a cube

• Finding the length of sides in a right-angled triangle

• Measuring the circumference of a rectangle

• Calculating the area of a circle

In a right-angled triangle, which side is always the hypotenuse?

• The side opposite the right angle

• The shortest side

• Any side can be the hypotenuse

• The side adjacent to the right angle

What is the formula for Pythagoras Theorem?

• a^2 - b^2 = c^2

• a^2 * b^2 = c^2

• a^2 + b^2 = c^2

• a^2 / b^2 = c^2

If the sides of a right-angled triangle are 2.1m and 7.9m, what is the hypotenuse?

• 8.17m

• 9.5m

• 10.2m

• 11.3m

What is the inverse operation of squaring a number?

• Square rooting

• Dividing

• Cubing

• Multiplying

How do you find a shorter side in a right-angled triangle?

• Multiply the squares of the other two sides

• Subtract the square of the hypotenuse from the square of the other side

• Divide the square of the hypotenuse by the other side

• Add the squares of the other two sides

What is the diagonal of a rectangle if the sides are 2m and 11m?

• 14.1m

• 13.2m

• 12.5m

• 11.18m

How is Pythagoras Theorem applied in 3D objects?

• To find the volume of the object

• To calculate the surface area

• To determine the diagonal of the object

• To measure the perimeter

What is the length of the diagonal in a cuboid with sides 16cm, 12cm, and 28cm?

• 36.2cm

• 34.4cm

• 32.1cm

• 30.5cm
