What is the special right triangle rule?
A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist. For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°. This is called an "angle-based" right triangle.

What are the side lengths of a 30 60 90?
30°-60°-90° Triangles There is a special relationship among the measures of the sides of a 30°−60°−90° triangle. A 30°−60°−90° triangle is commonly encountered right triangle whose sides are in the proportion 1:√3:2. The measures of the sides are x, x√3, and 2x.
How to find the missing side of a right triangle?
If you know two other sides of the right triangle, it's the easiest option; all you need to do is apply the Pythagorean theorem: a² + b² = c².
How to find area of a triangle?
As we remember from basic triangle area formula, we can calculate the area by multiplying triangle height and base and dividing the result by two . A right triangle is a special case of a scalene triangle, in which one leg is the height when the second leg is the base, so the equation gets simplified to:
How do you solve a right angle triangle with only one side?
To solve a triangle with one side, you also need one of the non-right angled angles. If not, it is impossible:
How to find side adjacent to angle?
Alternatively, multiply the hypotenuse by cos (θ) to get the side adjacent to the angle .
What is the symmetry of a right triangle?
If a right triangle is isosceles (i.e., its two non-hypotenuse sides are the same length) it has one line of symmetry. Otherwise, the triangle will have no lines of symmetry.
How are right angled triangles similar?
They are similar if all their angles are the same length, or if the ratio of 2 of their sides is the same.
How to find the hypotenuse of an angle?
If you have an angle and the side opposite to it, you can divide the side length by sin (θ) to get the hypotenuse. Alternatively, divide the length by tan (θ) to get the length of the side adjacent to the angle.
How to solve a triangle with 2 sides?
Step 1. Since we know 2 sides and 1 angle of this triangle, we can use either the Pythagorean theorem (by making use of the two sides) or use sohcahtoa (by making use of the angle and 1 of the given sides). Step 2. Step 2. Chose which way you want to solve this problem. There are several different solutions.
What is the name of the triangle with 1 side and 1 angle?
Since we know 1 side and 1 angle of this triangle, we will use sohcahtoa .
How to find the length of a hypotenuse?
Step 1. Step 1. Since we know 1 side and 1 angle of this triangle, we will use sohcahtoa . Step 2. Step 2. Set up an equation using the sine, cosine or tangent ratio Since we want to know the length of the hypotenuse, and we already know the side opposite of the 53° angle, we are dealing with sine.
What is the only thing you can't use to solve a sine problem?
The only thing you cannot use is sine, since the sine ratio does not involve the adjacent side, x, which we are trying to find.
How to solve for x in Pythagorean theorem?
Step 1. Step 1. Since we know 2 sides of this triangle, we will use the Pythagorean theorem to solve for x. Step 2. Rest of Steps. Substitute the two known sides into the Pythagorean theorem's formula : a 2 + b 2 = c 2 8 2 + 6 2 = x 2 100 = x 2 x = 100 x = 10.
Which theorem is used to solve for side t?
Since we know 2 sides of this triangle, we will use the Pythagorean theorem to solve for side t .
