What is called a triangle?

A simple closed curve or a polygon formed by three line-segments (sides) is called a triangle. The above shown shapes are triangles. The symbol of a triangle is ∆. A triangle is a polygon with three sides. ... Triangles can be classified on the basis of sides and angles.

What is the triangle rule?

The sides of a triangle rule asserts that the sum of the lengths of any two sides of a triangle has to be greater than the length of the third side. ... The sum of the lengths of the two shortest sides, 6 and 7, is 13. That length is greater than the length of the longest side, 8.

What are the 3 sides of a triangle?

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 many sides does a triangle have 4?

Every triangle has three sides and three angles, some of which may be the same.

What does ∆ mean in math?

change ∆: Means “change” or “difference”, as in the equation of a line's slope: 2. 1. 2.

What is triangle with example?

How do I find the third side of a triangle?

The Triangle Inequality theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.

1. So, difference of two sides

How can a triangle be formed?

All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.

What are the 7 triangles?
