Special Right Triangle Theorems
Special right triangles are right triangles with specific angle measures and side ratios. These triangles have unique properties that make them useful for solving problems involving right triangles.
Pythagorean Theorem
The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
a2+ b 2= c 2
where a and b are the lengths of the legs of the right triangle and c is the length of the hypotenuse.
30-60-90 Triangle Theorem
A 30-60-90 triangle is a right triangle with angles of 30°, 60°, and 90°. The side opposite the 30° angle is half the length of the hypotenuse, and the side opposite the 60° angle is √3times the length of the shorter leg.
- shorter leg: a
- longer leg: √3a
- hypotenuse: 2a
45-45-90 Triangle Theorem
A 45-45-90 triangle is a right triangle with angles of 45°, 45°, and 90°. The two legs of the triangle are equal in length, and the hypotenuse is √2times the length of either leg.
- legs: a
- hypotenuse: √2a

FAQ Explained
What is the Pythagorean theorem?
The Pythagorean theorem states that in a right 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.
How can I use the 30-60-90 triangle theorem to solve problems?
In a 30-60-90 triangle, the ratio of the side lengths is always 1:√3:2. This ratio can be used to find the length of any side if the length of another side is known.
What are some real-world applications of special right triangles?
Special right triangles are used in a variety of real-world applications, such as architecture, surveying, and navigation. For example, the Pythagorean theorem can be used to calculate the height of a building or the distance between two points on a map.
