Right Triangle
A triangle with one right angle
A right triangle is a type of triangle in which one of its angles measures exactly 90 degrees (a right angle). The other two angles are acute angles, measuring less than 90 degrees.
The side opposite to the right angle is called the hypotenuse, and it is the longest side of the triangle. The other two sides are called legs. The legs meet at the right angle and are perpendicular to each other.
The Pythagorean theorem is a fundamental tool for working with right triangles. It states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. That is, for a right triangle with legs a and b and hypotenuse c, the Pythagorean theorem can be written as follows:
c^2 = a^2 + b^2
Right triangles are used extensively in mathematics, science, and engineering. They have numerous applications, such as in trigonometry, where the sine, cosine, and tangent functions are defined based on the ratios of the sides of a right triangle. They also appear in many real-world problems, such as calculating the height of a building from the length of its shadow.
