The 45°-45°-90° 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°-45°-90°, follow a ratio of 1:1:√ 2. Like the 30°-60°-90° triangle, knowing one side length allows you to determine the lengths of the other sides of a 45°-45°-90° triangle.

A right triangle, sometimes called a right-angled triangle, is a trianglethat has one interior angle equal to exactly 90 degrees, forming what is called a right angle. The sides adjacent to the right angle are referred to as legs a and b, and are also often referred to as the base and height. The calculator uses the term height to represent the alt...
To calculate the length of the hypotenuse in a right triangle when you know the length of the two legs, you can use the Pythagorean theorem. The Pythagorean theorem states that side a squared plus side b squared is equal to side c squared. Note, keep in mind that sides a and b specifically refer to the legs, and side crefers to the hypotenuse. a² +...
To calculate the length of a missing side, you can use a known side and the hypotenuse and rearrange the Pythagorean theorem to solve the missing variable. For instance, to find leg b, rearrange the Pythagorean theorem to solve for b by subtracting a²from both sides. Then take the square root of the right side of the equation to isolate the missing...
If you know the lengths of two sides of a right triangle, then you can determine the interior angles using the trigonometric functions sine, cosine, and tangent. These are usually shortened to sin, cos, and tan. To find the angle given two side lengths, you can use the following formulas: In a right triangle, the adjacent side to θ is the side of t...
The formula to find the perimeterof a right triangle is: perimeter = a + b + c The perimeter is equal to leg a plus leg b plus hypotenuse c. You can use the formulas above to find the lengths of the missing leg or hypotenuse if any are missing.
There are a few types of special right triangles, which are triangles that have specific proportions. These special right triangles also have formulas to simplify solving them.
The sum of the three angles of a triangle is always 180 o. One of the angles has a measure of 90 o as it is a right triangle. 147∘ + x =180∘ x = 180∘ −147∘ x = 33∘. Simplify. Find the value of x. The third angle of the right triangle measures 33 o. There is an established convention for naming triangles.
The base and height area formula states: A = 1 2 bh. The triangle area A is equal to 1/2 times base b times height h. You can also use the three-sides method (SSS or side-side-side), which is also known as Heron’s formula. Heron’s formula states: s = a + b + c 2.
Jul 18, 2024 · Calculate the triangle side lengths if two of its angles are 60° each and one of the sides is 10 cm. The length of each side is 10 cm. Since two of the angles are 60° each, the third angle will be 180° - (60° + 60°) = 60°. As all the three angles are equal, the triangle is an equilateral triangle.

An equilateral triangle has all sides equal in length and all interior angles equal. Therefore there is no "largest" or "smallest" in this case. Isosceles triangles Isosceles triangles have two sides the same length and two equal interior angles. Therefore there can be two sides and angles that can be the "largest" or the "smallest".
