Introduction
In the realm of geometry, triangles are fundamental shapes that have been studied extensively. One of the most common types of triangles is the 45°-45°-90° triangle, also known as the isosceles right triangle. This triangle has two equal legs and a hypotenuse that is equal to the leg length multiplied by the square root of 2. In this article, we will delve into the relationship between the legs and the hypotenuse of a 45°-45°-90° triangle and explore how to find the length of one leg when the hypotenuse is given.
The Relationship Between Legs and Hypotenuse
A 45°-45°-90° triangle has two equal legs and a hypotenuse that is equal to the leg length multiplied by the square root of 2. This relationship can be expressed mathematically as:
c = a√2
where c is the length of the hypotenuse, a is the length of one leg, and √2 is the square root of 2.
Finding the Length of One Leg
Given the length of the hypotenuse, we can use the relationship above to find the length of one leg. Let's consider the problem at hand: the hypotenuse of a 45°-45°-90° triangle measures 22√2 units. We want to find the length of one leg.
Step 1: Write Down the Relationship Between Legs and Hypotenuse
We know that the length of the hypotenuse is equal to the leg length multiplied by the square root of 2. We can write this relationship as:
