Frequently Asked Questions

1. How Do You Find a Right-Angled Triangle? Use the Pythagorean theorem.

2. What is the 3 4 5 Rule for a Right Angle Triangle? A Pythagorean triple where sides are in the ratio 3:4:5.

3. How to Find Hypotenuse? \( c = \sqrt{a^2 + b^2} \).

4. What is the 30 60 90 Triangle? A special right triangle with angles 30, 60, and 90 degrees.

5. What is the 45 45 90 Rule? In this triangle, the legs are equal, and the hypotenuse is the leg length multiplied by \( \sqrt{2} \).

6. Can NPV be Negative? Not directly applicable to right triangle calculations.

7. How to Calculate Cash Flow? Not related to right triangle calculations but important in financial assessments.

8. What are the 2 Special Triangles? The 30-60-90 and 45-45-90 triangles.

9. What is the 45 45 90 rule? In a 45-45-90 triangle, the legs are of equal length, and the hypotenuse is the leg length multiplied by \( \sqrt{2} \).

10. What is a formula of triangle? The area of a triangle is \( \frac{1}{2} \times base \times height \). For right triangles, this can be simplified using the legs as base and height.

11. What are the 3 degrees of a right triangle? A right triangle always includes a 90-degree angle, with the other two angles adding up to 90 degrees.

12. What are the 12 types of triangles? Triangles can be classified based on sides (equilateral, isosceles, scalene) and angles (acute, right, obtuse).

13. How to find hypotenuse? Use the Pythagorean theorem: \( c = \sqrt{a^2 + b^2} \).

14. What is the 30 60 90 Triangle? A special right triangle with angles of 30, 60, and 90 degrees, known for its unique ratio of side lengths.

15. What are the 2 special triangles? The 30-60-90 triangle and the 45-45-90 triangle are two special right triangles with specific properties.

16. How to calculate discount rate? Though not directly related to triangles, the discount rate is often calculated using WACC or expected return based on investment risk.
