Introduction

Isosceles right triangles are a fundamental concept in geometry, and understanding their properties is essential for solving various mathematical problems. In this article, we will delve into the characteristics of isosceles right triangles and examine the given statements to determine which one is true.

What is an Isosceles Right Triangle?

An isosceles right triangle is a type of triangle that has two sides of equal length, and the third side is the hypotenuse. The two equal sides are called legs, and the hypotenuse is the side opposite the right angle. In an isosceles right triangle, the two legs are equal in length, and the hypotenuse is the longest side.

Properties of Isosceles Right Triangles

Isosceles right triangles have several unique properties that make them easier to work with. Some of the key properties include:

  • Equal Legs: The two legs of an isosceles right triangle are equal in length.
  • Right Angle: The angle between the two legs is a right angle, which is 90 degrees.
  • Hypotenuse: The hypotenuse is the longest side of the triangle and is opposite the right angle.
  • Pythagorean Theorem: The Pythagorean theorem states that the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse.

Analyzing the Statements

Now that we have a good understanding of isosceles right triangles, let's analyze the given statements to determine which one is true.

A. The hypotenuse is 2\sqrt{2} times as long as either leg.

To determine if this statement is true, we need to consider the properties of isosceles right triangles. Since the two legs are equal in length, we can let the length of each leg be xx. Using the Pythagorean theorem, we can find the length of the hypotenuse:

x2+x2=(2x)2x^2 + x^2 = (\sqrt{2}x)^2

Simplifying the equation, we get:

2x2=2x22x^2 = 2x^2

This equation is true, which means that the hypotenuse is indeed 2\sqrt{2} times as long as either leg.

B. The hypotenuse is 3\sqrt{3} times as long as either leg.

To determine if this statement is true, we need to consider the properties of isosceles right triangles. Since the two legs are equal in length, we can let the length of each leg be xx. Using the Pythagorean theorem, we can find the length of the hypotenuse:

x2+x2=(3x)2x^2 + x^2 = (\sqrt{3}x)^2

Simplifying the equation, we get:

2x2=3x22x^2 = 3x^2

This equation is not true, which means that the hypotenuse is not 3\sqrt{3} times as long as either leg.

C. Each leg is 2\sqrt{2} times as long as the hypotenuse.

To determine if this statement is true, we need to consider the properties of isosceles right triangles. Since the two legs are equal in length, we can let the length of each leg be xx. Using the Pythagorean theorem, we can find the length of the hypotenuse:

x2+x2=(2x)2x^2 + x^2 = (\sqrt{2}x)^2

Simplifying the equation, we get:

2x2=2x22x^2 = 2x^2

This equation is true, which means that each leg is indeed 2\sqrt{2} times as long as the hypotenuse.

Conclusion

In conclusion, the true statement about an isosceles right triangle is:

  • A. The hypotenuse is 2\sqrt{2} times as long as either leg.

This statement is true because the hypotenuse is indeed 2\sqrt{2} times as long as either leg, as demonstrated by the Pythagorean theorem.

Final Thoughts

Isosceles right triangles are a fundamental concept in geometry, and understanding their properties is essential for solving various mathematical problems. By analyzing the given statements, we have determined that the hypotenuse is 2\sqrt{2} times as long as either leg. This knowledge can be applied to a wide range of mathematical problems, from solving triangles to understanding the properties of shapes.
