Find The Unknown Value In The Given Figure. 6cm 10cm
Introduction
In geometry, finding the unknown value in a given figure is a common problem that requires the application of various mathematical concepts and formulas. In this article, we will discuss how to find the unknown value in a geometric figure using basic geometry concepts and formulas.
Understanding the Problem
The problem we are going to solve is a simple geometric problem that involves finding the unknown value in a figure with two known sides. The figure is a rectangle with two sides measuring 6cm and 10cm.

Finding the Unknown Value
To find the unknown value, we need to use the basic geometry concept of the Pythagorean theorem. The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Applying the Pythagorean Theorem
In this case, we can apply the Pythagorean theorem to find the unknown value. Let's call the unknown value 'x'. We can write the equation as:
x^2 + 6^2 = 10^2
Solving the Equation
Now, we need to solve the equation to find the value of 'x'. We can start by expanding the equation:
x^2 + 36 = 100
Next, we can subtract 36 from both sides of the equation:
x^2 = 64
Finally, we can take the square root of both sides of the equation to find the value of 'x':
x = √64 x = 8
Conclusion
In this article, we discussed how to find the unknown value in a geometric figure using basic geometry concepts and formulas. We applied the Pythagorean theorem to find the unknown value in a rectangle with two known sides. The unknown value was found to be 8cm.

Conclusion
Q: What is the Pythagorean theorem?
A: The Pythagorean theorem is a fundamental concept in geometry that states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Q: How do I apply the Pythagorean theorem to find the unknown value in a geometric figure?
A: To apply the Pythagorean theorem, you need to identify the right-angled triangle in the figure and label the sides. Then, you can use the formula a^2 + b^2 = c^2, where a and b are the lengths of the two sides and c is the length of the hypotenuse.
Q: What is the difference between a right-angled triangle and an oblique triangle?
A: A right-angled triangle is a triangle with one right angle (90 degrees), while an oblique triangle is a triangle with no right angles.
Q: Can I use the Pythagorean theorem to find the unknown value in an oblique triangle?
A: No, the Pythagorean theorem only applies to right-angled triangles. To find the unknown value in an oblique triangle, you need to use other geometric concepts and formulas.
Q: How do I use algebraic manipulations to solve the equation and find the value of the unknown variable?
A: To use algebraic manipulations, you need to isolate the unknown variable on one side of the equation. You can do this by adding, subtracting, multiplying, or dividing both sides of the equation by the same value.
Q: What are some common mistakes to avoid when finding the unknown value in a geometric figure?
A: Some common mistakes to avoid include:
- Not reading the problem carefully and understanding what is being asked.
- Not using basic geometry concepts and formulas to solve the problem.
- Not applying the Pythagorean theorem to find the unknown value in a right-angled triangle.
- Not using algebraic manipulations to solve the equation and find the value of the unknown variable.
Q: Can I use a calculator to find the unknown value in a geometric figure?
