The area of a right triangle is calculated using the formula, Area of a right triangle = 1/2 × base × height.

In a right triangle, (Hypotenuse) 2 = (Base) 2 + (Altitude) 2.

The other two legs are perpendicular to each other one is the base and the other is the height.

In a right triangle, the hypotenuse is the side opposite to the right angle and is the longest side of the triangle.

The side lengths of a right-angled triangle always satisfy the Pythagoras theorem.

Listed here are some of the important tips and tricks related to a right triangle. The side opposite to the 30º angle is the shortest side. There is also a special case of a scalene triangle 30º-60º-90º which is also a right triangle where the ratio of the triangle's longest side to its shortest side is 2:1. PQ is not equal to QR, hence, it is a scalene triangle. In the triangle PQR given below, ∠Q = 90º, hence, it is a right triangle. Scalene Right TriangleĪ scalene right triangle is a triangle where one angle is 90° and the other two angles are of different measurements.

So in an isosceles right triangle, the angles are always 90º-45º- 45º. Hence, the base angles add up to 90º which implies that they are 45º each. We know that the sum of the angles of a triangle is 180º. Since two sides are equal, the triangle is also an isosceles triangle. Observe the triangle ABC given below in which angle A = 90º, and we can see that AB = AC. Isosceles Right TriangleĪn isosceles right triangle is called a 90º-45º- 45º triangle.

A triangle in which one angle is 90º and the other two angles are equal is referred to as an isosceles right triangle, and the triangle in which the other two angles have different values is called a scalene right triangle. There are a few special right triangles such as the isosceles right triangles and the scalene right triangles. This implies that the other two angles in the triangle will be acute angles. We have learned that one of the angles in a right triangle is 90º. Some of the examples of right triangles in our daily life are the triangular slice of bread, a square piece of paper folder across the diagonal, or the 30-60-90 triangular scale in a geometry box. The side BC opposite to the right angle is called the hypotenuse and it is the longest side of the right triangle.AC is the height, altitude, or perpendicular.Now, let us understand the distinct features of a right triangle referring to the triangle ABC given above.

The definition for a right triangle states that if one of the angles of a triangle is a right angle - 90º, the triangle is called a right-angled triangle or a right triangle. Here AB is the base, AC is the altitude, and BC is the hypotenuse. Observe the right-angled triangle ABC given below which shows the base, the altitude, and the hypotenuse. The side opposite to the right angle is the longest side and is referred to as the hypotenuse. In this triangle, the relationship between the various sides can be easily understood with the help of the Pythagoras theorem. A right triangle is a triangle in which one angle is 90°.
