## What makes a triangle unique?

correspondence; three side lengths of a triangle determine a unique triangle. equal under some correspondence; two sides and an included angle of a triangle determine a unique triangle.

## What is congruent triangle?

Two triangles are congruent if their corresponding sides are equal in length, and their corresponding angles are equal in measure.

## What are the angles inside a triangle called?

The angles inside a triangle are called interior angles. The diagram below shows the interior and exterior angles of a triangle. The three interior angles in a triangle will always add up to 180°. At each corner the exterior and interior angles are on a straight line, so at each corner these two angles add up to 180°.

## What are the 7 types of triangles?

To learn about and construct the seven types of triangles that exist in the world: equilateral, right isosceles, obtuse isosceles, acute isosceles, right scalene, obtuse scalene, and acute scalene.

## How many triangles do we have?

## How many vertices are there in a triangle?

3Triangle/Number of vertices

## What is a true triangle?

A triangle has three sides, three vertices, and three angles. The sum of the three interior angles of a triangle is always 180°. The sum of the length of two sides of a triangle is always greater than the length of the third side.

## What is special about a triangle?

But triangles aren’t just mathematically significant, they are also fundamental to the way we build our environments, both physical and virtual. Triangles are special because they are exceptionally strong. Out of all the two-dimensional shapes we can make out of straight struts of metal, only a triangle is rigid.

## How do you name a triangle?

There is an established convention for naming triangles. The labels of the vertices of the triangle, which are generally capital letters, are used to name a triangle. You can call this triangle ABC or since A, B, and C are vertices of the triangle. When naming the triangle, you can begin with any vertex.

## What is Triangle explain?

A triangle is a shape, or a part of two dimensional space. It has three straight sides and three vertices. The three angles of a triangle always add up to 180° (180 degrees). It is the polygon with the least possible number of sides.

## What is a half triangle called?

A triangle with all sides equal is called equilateral, a triangle with two sides equal is called isosceles, and a triangle with all sides a different length is called scalene. A triangle can be simultaneously right and isosceles, in which case it is known as an isosceles right triangle.
