# What does an equilateral triangle sides add up to?

## What does an equilateral triangle sides add up to?

Explanation: Since this is an equilateral triangle, all of the sides and all of the angles would be equal (60 degrees each since the 3 angles must add up to 180 degrees).

## How do you find the sides of an equilateral triangle?

Formulas and Calculations for a equilateral triangle: Altitude of Equilateral Triangle h = (1/2) * √3 * a. Angles of Equilateral Triangle: A = B = C = 60° Sides of Equilateral Triangle: a = b = c.

Do equilateral triangles have equal sides?

Equilateral. An equilateral triangle has three equal sides and angles. It will always have angles of 60° in each corner.

### What does 2 equilateral triangles make?

Two equilateral triangles are inscribed into a square as shown in the diagram. Their side lines cut the square into a quadrilateral and a few triangles.

### What is the length of each side of an equilateral triangle having an area of 9 root 3 cm square?

36 cm
The length of each side of an equilateral triangle having an area of 9√3cm2 is. 36 cm.

What is the area of an equilateral triangle with sides √ 3 4?

Therefore, the area of the equilateral triangle (√3/4) × 42 = 4√3 square units.

#### What are the three sides of a triangle called?

In a right triangle, the hypotenuse is the longest side, an “opposite” side is the one across from a given angle, and an “adjacent” side is next to a given angle. We use special words to describe the sides of right triangles.

#### How does an equilateral triangle look like?

An equilateral triangle has three equal sides and three equal angles (which are each 60°). You don’t often hear the expression equiangular triangle, however, because the only triangle that’s equiangular is the equilateral triangle, and everyone calls this triangle equilateral.

How do you find the height of an equilateral triangle with 3 sides?

Formula to calculate height of an equilateral triangle is given as: Height of an equilateral triangle, h = (√3/2)a, where a is the side of the equilateral triangle.

## How do you find the angle of an equilateral triangle?

If you know 2 angles of a triangle, you can always subtract their sum from 180 to find the third angle. Every angle of an equilateral triangle is always 60 degrees. For isosceles triangles, it is important to remember that the two equal sides will face the two equal angles (so if angle A = angle B, side A = side B).

## What are the properties of an equilateral triangle?

All equilateral triangles have these properties in common: The three sides of any equilateral triangle are equal. The three angles of any equilateral triangle all measure 60 degrees.

What is the equation for an equilateral triangle?

The height of an equilateral triangle is equal to the square root of three divided by two and multiplied by the length. The equation for the height of an equilateral triangle is based on the Pythagorean Theorem.

### What is an example of an equilateral triangle?

An equilateral triangle is an example of a CONVEX polygon. An equilateral triangle is a triangle that has the same side length and same angles. It is identified as a convex polygon because it does not have a reflex angle.
