Understanding Special Right Triangles
Special right triangles are a fundamental concept in geometry, and they play a crucial role in various mathematical and real-world applications. In this blog post, we will delve into the world of special right triangles, exploring their properties, and providing essential practice problems to help you master this concept.
Properties of Special Right Triangles
There are two types of special right triangles: 30-60-90 triangles and 45-45-90 triangles. These triangles have unique properties that make them extremely useful in solving various geometric problems.
- 30-60-90 Triangles: In a 30-60-90 triangle, the side opposite the 30-degree angle is half the length of the hypotenuse, and the side opposite the 60-degree angle is √3 times the length of the shorter side.
- 45-45-90 Triangles: In a 45-45-90 triangle, the two legs are equal in length, and the hypotenuse is √2 times the length of either leg.
Practice Problems
Now that we have explored the properties of special right triangles, it’s time to put your knowledge into practice. Here are five essential practice problems to help you master this concept:
Problem 1
In a 30-60-90 triangle, the length of the shorter side is 4 cm. What is the length of the hypotenuse?
📝 Note: Use the properties of 30-60-90 triangles to solve this problem.
Answer: 8 cm
Problem 2
In a 45-45-90 triangle, the length of one leg is 5 cm. What is the length of the hypotenuse?
📝 Note: Use the properties of 45-45-90 triangles to solve this problem.
Answer: 5√2 cm
Problem 3
A right triangle has angles measuring 30, 60, and 90 degrees. If the length of the side opposite the 60-degree angle is 6√3 cm, what is the length of the side opposite the 30-degree angle?
📝 Note: Use the properties of 30-60-90 triangles to solve this problem.
Answer: 6 cm
Problem 4
A right triangle has angles measuring 45, 45, and 90 degrees. If the length of the hypotenuse is 10√2 cm, what is the length of one leg?
📝 Note: Use the properties of 45-45-90 triangles to solve this problem.
Answer: 10 cm
Problem 5
A right triangle has angles measuring 30, 60, and 90 degrees. If the length of the hypotenuse is 12 cm, what is the length of the side opposite the 60-degree angle?
📝 Note: Use the properties of 30-60-90 triangles to solve this problem.
Answer: 6√3 cm
