How do you find the area of a triangle with 3 sides?

What is the Area of Triangle with 3 Sides Equal? If a triangle has 3 equal sides, it is called an equilateral triangle. The area of an equilateral triangle can be calculated using the formula, Area = a2(√3/4), where ‘a’ is the side of the triangle.

Can you solve a triangle with 3 sides?

“SSS” is when we know three sides of the triangle, and want to find the missing angles. To solve an SSS triangle: use The Law of Cosines first to calculate one of the angles. then use The Law of Cosines again to find another angle.

What is a triangle with 3 equal side lengths?

A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides and angles equal.

How do we find area of a triangle?

So, the area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle. Example: Find the area of the triangle. The area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.

How do you find the area of an irregular shape with 4 sides?

The area of any irregular quadrilateral can be calculated by dividing it into triangles. Example: Find the area of a quadrilateral ABCD whose sides are 9 m, 40 m, 28 m and 15 m respectively and the angle between the first two sides is a right angle. The area of the quadrilateral ABCD =(180+126)=306 square meters.

How do you calculate an uneven area?

How to use irregular area calculator?

Step 1: Measure all sides of the area in one unit (Feet, Meter, Inches or any other).
Step 2: Enter length of horizontal sides into Length 1 and Length 2. And Width of the vertical sides into Width 1 and Width 2.
Step 3: Press calculate button.
Our Formula: Area = b × h.

How do you find the side of a triangle given two sides?

Boundless Algebra

The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , can be used to find the length of any side of a right triangle.
The side opposite the right angle is called the hypotenuse (side c in the figure).

What is the shortest side of a 30 60 90 triangle?

And so on. The side opposite the 30° angle is always the smallest, because 30 degrees is the smallest angle. The side opposite the 60° angle will be the middle length, because 60 degrees is the mid-sized degree angle in this triangle.

How do you classify a triangle by side lengths?

Classifying Triangles by Side Lengths

An equilateral triangle has side lengths that are the same. Here is an example.
A scalene triangle is a triangle where the lengths of all three sides are different.
An isosceles triangle has two side lengths that are the same and one side length that is different.

How do you classify a triangle using side lengths?

Equilateral triangle: A triangle with three sides of equal length. Isosceles triangle: A triangle with at least two sides of equal length. Line of symmetry: A line through a figure that creates two halves that match exactly. Obtuse angle: An angle with a measure greater than 90 degrees but less than 180 degrees.

What are the formulas for triangles?

The area formulas for all the different types of triangles like the equilateral triangle, right-angled triangle, and isosceles triangle are given below….Area of an Isosceles Triangle:

Given Dimensions	Area of a Triangle Formula
When base and height is given.	Area of a right triangle = 1/2 × Base × Height
