The Formula for a Right-Angled Triangle Pythagoras theorem Pythagoras discovered that the hypotenuse square equals the sum of the squares of the other two sides in a right-angled triangle. The perimeter of a right triangle The perimeter of a right-angled triangle is defined as the total length ...
Is the Right-Angled Triangle a Key? The Cos Theta Formula is especially useful when working with right-angled triangles. In a right triangle, the Cosine of an angle will always be the length of the adjacent side divided by the length of the hypotenuse. This makes it a great tool for sol...

Solved Examples for Right Triangle Formula Q.1: The length of two sides of a right-angled triangle is given as 6 cm and 8 cm. Compute the following: Length of its hypotenuse The perimeter of the triangle Area of the triangle Solution: Given parameters are: ...
The Pythagorean theorem states that the adjacent and opposite sides of a right triangle squared add up to equal the square root of the hypotenuse. The equation is: Hypotenuse formula Trigonometric Ratios There are three sides to every triangle, is the hypotenuse the longest side for a right ...
Example 1:Find the value of the tangent function in a right-angled triangle when the adjacent side = 3 units, opposite side = 4 units, and hypotenuse = 5 units. Solution:Using the formula of the tangent function, we have tan x = opposite side/adjacent side ...
In a right-angled triangle, the sine of an angle is the length of the opposite side, divided by the length of the triangle's hypotenuse. Depending upon the quadrants, the sine function can have both positive as well as negative values. Sine has a positive value in the first and second ...
half of the rectangle is a right-angled triangle as it can be seen from the figure above. thereby, applying the pythagoras theorem: ⇒ a 2 = h 2 + (a/2) 2 ⇒ h 2 = (3/4)a 2 ⇒ h = (√3/2)a ………(ii) substituting the value of (ii) in (i), we...
The ratios of the sides of a right triangle are known as trigonometric ratios. Sin, cos, tan, cot, sec and cosec are the six main trigonometric ratios. The formulae for each of these ratios are different. It takes advantage of a right-angled triangle’s three sides and angles. Let’s...
