Right Angled Triangle. A right-angled triangle is a type of triangle that has one of its angles equal to 90 degrees. The other two angles sum up to 90 degrees. The sides that include the right angle are perpendicular and the base of the triangle. The third side is called the hypotenuse, which is the longest side of all three sides.

The right angle is always the largest angle in a right triangle.The hypotenuse, the side opposite the right angle, is the longest side.There can’t be any obtuse angles in a right triangle.Broadly, right triangles can be categorized as: 1. Isosceles right triangle: In this triangle, one interior angle measures 90°, and the other two angles measure 45° each. It is also known as a 45-90-45 triangle. This is an isosceles right triangle, with the sides AB and AC equal and ∠B measuring 90°. Here, ∠A and ∠Cmeasure 45° each because the prop...
Pythagoras theorem
1. 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 of the boundary. The formula for perimeter is: P (perimeter) = a + b + c(sum of the sides of a triangle)
Area of a right-angled triangle
The area of a right-angled triangle is defined as the space occupied by the triangle. The formula for the area is: Area = 12×base×height
The largest side of a triangle is 10 cm. If the height of the triangle is 8 cm, determine the area using the Pythagorean theorem.
It has no equal sides so it is a scalene right-angled triangle And, like all triangles, the three angles always add up to 180° . 6701, 6707, 761, 1800, 762, 1801, 3228, 3229, 8997, 8998
A right triangle or right-angled triangle, sometimes called an orthogonal triangle or rectangular triangle, is a triangle in which two sides are perpendicular, forming a right angle (1 ⁄ 4 turn or 90 degrees). The side opposite to the right angle is called the hypotenuse (side in the figure).
- Right Triangle Definition. A triangle with any interior angle equal to 90° is called a Right Triangle. The sum of all the interior angles of the triangle is 180° which is called the Angle Sum Property of a Triangle.
- Properties of Right Angled Triangle. A Right Angled Triangle has the following key properties : One of the angles in a right-angled triangle is exactly 90 degrees.
- Right Triangle Formula. The formula for the right-angled triangle is given by the Pythagoras Theorem. According to the pythagoras theorem, in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
- Perimeter of Right Triangle. The perimeter of the right triangle shown above is equal to the sum of the sides, BC + AC + AB = (a + b + c) units. The perimeter is a linear value with a unit of length.
A right triangle is a triangle with one of the angles as 90 degrees. Study Right Triangle in Geometry with concepts, different types of right triangles, Pythagorean triplets, and understand more about the right triangle with solved examples and practice questions.
Jan 10, 2024 · A right triangle, or a right-angled triangle, as the name suggests, is a special kind of triangle that carries a distinct feature – one of its internal angles measures exactly 90 degrees. This specific angle is referred to as the right angle.
