The area of a right-angled triangle is defined as the space occupied by the triangle.Selina Solutions for Concise Mathematics Class 9 ICSE Chapterwise List - Free P (perimeter) = a + b + c (sum of the sides of a triangle) Area of a right-angled triangle The perimeter of a right-angled triangle is defined as the total length of the boundary. Pythagoras discovered that the hypotenuse square equals the sum of the squares of the other two sides in a right-angled triangle.The Formula for a Right-Angled Triangle Pythagoras theorem In this triangle, all the three sides will be of different lengths, and the three angles will be of different measures. In the scalene right triangle ABC, ∠ A measures 30°, ∠ B measures 90°, and ∠ C measures 60°.

Scalene right triangle: This triangle is the one in which one interior angle measures 90°, while the other two have different measures.

Here, ∠ A and ∠ C measure 45° each because the property states that angles opposite to equal sides are also equal.Ģ. This is an isosceles right triangle, with the sides AB and AC equal and ∠ B measuring 90°. Isosceles right triangle: In this triangle, one interior angle measures 90°, and the other two angles measure 45° each. There can’t be any obtuse angles in a right triangle.īroadly, right triangles can be categorized as:ġ.The hypotenuse, the side opposite the right angle, is the longest side.

The right angle is always the largest angle in a right triangle.

The units m 2, cm 2, in 2, yd 2, and others commonly represent the area. The total space or territory covered by a right-angled triangle is known as the area of a right triangle. The longest side of the right triangle, which is also the side opposite the right angle, is the hypotenuse and the two arms of the right angle are the height and the base. A triangle in which one of the interior angles is 90° is called a right triangle.
