## What is a true triangle?

A triangle is a polygon with three edges and three vertices.

It is one of the basic shapes in geometry.

A triangle with vertices A, B, and C is denoted ..

## 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.

## What is a point of origin?

: the place where something comes from : the place where something originates The package’s point of origin was somewhere in the U.S. the point of origin of the fire that burned the building down.

## What is the rule for a 90 degree clockwise rotation?

Rule : When we rotate a figure of 90 degrees clockwise, each point of the given figure has to be changed from (x, y) to (y, -x) and graph the rotated figure. Let us look at some examples to understand how 90 degree clockwise rotation can be done on a figure.

## What is the name of Triangle?

Name of TriangleDescriptionEquilateral TriangleA triangle whose three sides have the same length. These sides of equal length are called congruent sides.Isosceles TriangleA triangle with exactly two congruent sides.Scalene TriangleA triangle in which all three sides are a different length.

## What is the point 00 called?

In economics we will usually give the axes different names, such as Price and Quantity. The point where the two axes intersect is called the origin. The origin is also identified as the point (0, 0).

## Is clockwise left or right?

Clockwise is spinning in the direction of an analog clock. It is a way to describe circular motion. Left or Right turns are ways of describing a change in approach. Clockwise is constantly turning to the right.

## What are the 5 properties of a triangle?

Properties of a TriangleA 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.A triangle with vertices P, Q, and R is denoted as △PQR.More items…

## Who invented the 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.

## Why is 0 0 called the origin?

The vertical axis is called the y-axis. The point at which the two axes intersect is called the origin. The origin is at 0 on the x-axis and 0 on the y-axis. … Since the origin has an x-coordinate of 0 and a y-coordinate of 0, its ordered pair is written (0, 0).

## What is the rule for a 90 degree rotation?

90 Degree Rotation When rotating a point 90 degrees counterclockwise about the origin our point A(x,y) becomes A'(-y,x). In other words, switch x and y and make y negative.

## What is the longest side of a triangle?

hypotenuseIn geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle.

## What are the sides of a right triangle?

A right triangle consists of two legs and a hypotenuse. The two legs meet at a 90° angle and the hypotenuse is the longest side of the right triangle and is the side opposite the right angle. There are a couple of special types of right triangles, like the 45°-45° right triangles and the 30°-60° right triangle.

## Does the origin always have to be at 0 0?

In a Cartesian coordinate system, the origin is the point where the axes of the system intersect. … The coordinates of the origin are always all zero, for example (0,0) in two dimensions and (0,0,0) in three.

## What are the 3 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.

## 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.

## 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.

## What are 2 attributes of a triangle?

Triangles are polygons with the least possible number of sides (three). The three internal angles of a triangle always add to 180 degrees. An equilateral triangle has three sides of equal length and three equal angles. An isosceles triangle has two sides of equal length and two equal angles.

## What type of angle is a triangle?
