FAQs on Formulas of Triangles - 3 Video Lecture - Crash Course for GRE

1. How do you find the area of a triangle using the formula?
Ans. To find the area of a triangle, you can use the formula A = 1/2 * base * height. Simply multiply the base of the triangle by the height, and then divide the result by 2.
2. What is the Pythagorean Theorem and how is it related to triangles?
Ans. The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. This theorem is commonly used to find the lengths of the sides of right triangles.
3. How do you calculate the perimeter of a triangle?
Ans. To calculate the perimeter of a triangle, simply add together the lengths of all three sides of the triangle. This will give you the total distance around the triangle.
4. Can you find the height of a triangle if you know the area and base length?
Ans. Yes, you can find the height of a triangle if you know the area and base length. Simply rearrange the formula for the area of a triangle (A = 1/2 * base * height) to solve for the height: height = 2 * Area / base.
5. What is the formula to find the length of a side in a triangle using trigonometry?
Ans. The formula to find the length of a side in a triangle using trigonometry is the Law of Cosines: c^2 = a^2 + b^2 - 2ab * cos(C), where c is the length of the side opposite the angle C, and a and b are the lengths of the other two sides.
