## What is a long triangle called?

The sides of a right triangle have different names: The longest side, opposite the right angle, is called the hypotenuse.

In the diagram, the hypotenuse is labelled c.

The other two sides are called the legs of the triangle..

## Which Triangle Cannot be drawn?

According to the first triangle inequality theorem, the lengths of any two sides of a triangle must add up to more than the length of the third side. This means that you cannot draw a triangle that has side lengths 2, 7 and 12, for instance, since 2 + 7 is less than 12.

## How many properties of Triangle are there?

## What are 10 geometric concepts?

Geometry is the fourth math course in high school and will guide you through among other things points, lines, planes, angles, parallel lines, triangles, similarity, trigonometry, quadrilaterals, transformations, circles and area.

## What is a distinct triangle?

distinct triangles. The number of distinct triangles constructed by choosing three vertices from among the corners of a unit cube = . Answer: Alternative solution. We construct a triangle from any three corners of the cube because they are not collinear.

## How many types of triangles are there based on angles?

An acute triangle has three angles that each measure less than 90 degrees. An equilateral triangle is a triangle in which all three sides are the same length. An obtuse triangle is a triangle with one angle that is greater than 90 degrees. A right triangle is a triangle with one 90 degree angle.

## What is called triangle?

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.

## Which is best definition of a triangle?

In geometry, a triangle is a closed, two-dimensional shape with three straight sides. A triangle is also a polygon.

## Who invented triangle?

Blaise PascalIt was invented by Blaise Pascal in 1653. Pascal’s triangle was invented by Blaise Pascal (1623-1662) in 1653. Although it has been named after blaise pascal, there have been traces of the triangle, long before Blaise Pascal was born.

## What is a triangle with 2 congruent sides?

When a triangle has two congruent sides it is called an isosceles triangle. The angles opposite to the two sides of the same length are congruent. A triangle without any congruent sides or angles is called a scalene triangle.

## What are the triangle types?

What are the types of triangle?The sum of angles in any triangle is 180°. … An equilateral triangle has three equal sides and angles. … An isosceles triangle can be drawn in many different ways. … A right-angled triangle has one 90° angle. … A scalene triangle has three different angles and none of its sides are equal in length.More items…
