How to work out if a triangle is right angled

Web2 days ago · There are three methods that can be used to discover the area of a triangle. Method 1. Using the perpendicular height The area of a triangle can be determined by multiplying half the length of its base by the perpendicular height. Perpendicular means at right angles. But which side is the base? Well, you can use any of the three sides. WebMethod 2: When the side lengths are not given but the right-angled triangle is drawn to scale. In this case, we use a ruler to measure the sides and add the measurements of each side. The perimeter of the right-angled triangle = sum of all the sides measured by the ruler. Method 3: When any two sides of a right-angled triangle are given.
