The perimeter of a triangle is equal to the sum of all the sides of the triangle, and the formula is expressed as, Perimeter of a triangle formula, P = (a + b + c), where 'a', 'b', and 'c' are the three sides of the triangle. The equilateral triangle formula for perimeter is, Perimeter of equilateral triangle = (a +a + a) = 3a.

Step 1: Enter the values of any two angles and any one side of a triangle below which you want to solve for remaining angle and sides. Triangle calculator finds the values of remaining sides and angles by using Sine Law. Sine law states that a sinA = b sinB = c sinC a sin A = b sin B = c sin C Cosine law states that-

In mathematics, the Pythagorean theorem or Pythagoras' theorem is a fundamental relation in Euclidean geometry between the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides.

Angles Add to 180°: A + B + C = 180°. When you know two angles you can find the third. 2. Law of Sines (the Sine Rule): a sin (A) = b sin (B) = c sin (C) When there is an angle opposite a side, this equation comes to the rescue. Note: angle A is opposite side a, B is opposite b, and C is opposite c. 3.

Given two sides 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 If leg a is the missing side, then transform the equation to the form where a is on one side and take a square root: a = √ (c² - b²) If leg b is unknown, then: b = √ (c² - a²)
Which of the following is an obtuse triangle? A. Triangle B B. Triangle A C. Triangle D D
Naming angles and vertices Referencing the above triangles, an interior angle is formed at each vertex of a triangle. These angles share the same name as their vertices. Thus, the three interior angles for ABC above are A, B, and C. Triangle sides, angles, and congruence

Where a and b are two sides of a triangle, and c is the hypotenuse, the Pythagorean theorem can be written as: a 2 + b 2 = c 2. EX: Given a = 3, c = 5, find b: 3 2 + b 2 = 5 2 9 + b 2 = 25 b 2 = 16 b = 4. Law of sines: the ratio of the length of a side of a triangle to the sine of its opposite angle is constant. Using the law of sines makes it.
