# How to calculate right angled triangle Area of a Right Triangle Calculator

Step 1 The two sides we know are A djacent (6,) and H ypotenuse (8,). Step 2 SOH CAH TOA tells us we must use C osine. Step 3 Calculate Adjacent / Hypotenuse = 6,/8, = Step 4 Find the angle from your calculator using cos-1 of cos a° = 6,/8, = The 45°°° triangle, also referred to as an isosceles right triangle, since it has two sides of equal lengths, is a right triangle in which the sides corresponding to the angles, 45°°°, follow a ratio of v 2. Like the 30°°° triangle, knowing one side length allows you to determine the lengths of the other sides of a 45°°° triangle.

If you are wondering how to find right triangle area, you're in the right place - this area of a right triangle calculator is a tool for you. Whether you're looking for the equation given triangle legs, leg and hypotenuse or side and angle, you won't be disappointed - this calculator has all of them implemented. Scroll down to find out more about area of right triangle formulas or simply give our calculator a try!

Because the right triangle legs are perpendicular to each other, one leg is taken as a base and the other is a right triangle height:. If you have one leg and hypotenuse given, use the Pythagorean theorem to find the missing leg:. Then take a square root of the transformed equation:. If you know one angle and hypotenuseyou can use the law of sines :.

If you've just noticed that your triangle is not a right triangle, check out this general triangle area tool. One leg is a base and the other is the height - there is a right angle between them. So the area of an isosceles right triangle is:. Embed Share via. Equilateral Triangle.
