FAQs

How do you find the answer to a special right triangle? ›

To solve a 30° 60° 90° special right triangle, follow these steps:
  1. Find the length of the shorter leg. We'll call this x .
  2. The longer leg will be equal to x√3 .
  3. Its hypotenuse will be equal to 2x .
  4. The area is A = x²√3/2 .
  5. Lastly, the perimeter is P = x(3 + √3) .

How many special triangles are there? ›

There are three types of special right triangles. 30-60-90 triangles have side ratios of. 45-45-90 triangles have side ratios of. Pythagorean triple triangles have integer side lengths and include examples such as (3, 4, 5), (5, 12, 13), and (7, 24, 25).

What are the special right triangles in geometry notes? ›

There are two "special" right triangles that will continually appear throughout your study of mathematics: the 30º-60º-90º triangle and the 45º-45º-90º triangle. The special nature of these triangles is their ability to yield exact answers instead of decimal approximations when dealing with trigonometric functions.

How to tell if a triangle is 30 60 90 or 45 45 90? ›

A 45 45 90 triangle is isosceles. The two legs are equal. A 30 60 90 triangle has the hypotenuse 2 times as long as the short leg. Hope this helps!

What is the formula for a right triangle? ›

FAQs on Right Triangle Formulas

These formulas are given as: Pythagoras Theorem - Formula: (Hypotenuse)2 = (Perpendicular)2 + (Base) Area of a right triangle formula: Area = 1/2 × Base × Height. Perimeter of a right triangle formula = Sum of lengths of 3 sides.

How to find hypotenuse? ›

To find the hypotenuse, add the squares of the other sides, then take the square root. To find a shorter side, subtract the squares of the other sides, then take the square root.

How to know which special triangle to use? ›

You can use the special right triangles whenever an angle is a multiple of either π6 radians (= 30∘ ) or π4 ( =45∘ ).

How to find the angle of a triangle? ›

The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. Another way to calculate the exterior angle of a triangle is to subtract the angle of the vertex of interest from 180°.

How to similar triangles? ›

Two triangles are similar if they meet one of the following criteria. : Two pairs of corresponding angles are equal. : Three pairs of corresponding sides are proportional.

Which special right triangle uses √3? ›

30°⁠π/6√3
45°⁠π/4⁠1
60°⁠π/3⁠⁠1/√3⁠
90°⁠π/2⁠0

What is the formula for solving a right triangle? ›

Solving right triangles
  • Pythagorean theorem: a2 + b2 = c2.
  • Sines: sin A = a/c, sin B = b/c.
  • Cosines: cos A = b/c, cos B = a/c.
  • Tangents: tan A = a/b, tan B = b/a.
