## How do you find the area of a triangle in a square?

Area of a Triangle Formula. The general formula for calculating the area of a triangle is; Area (A) = ½ (b × h) square units, where; A is the area, b is the base, and h is the triangle’s height. The triangles might be different in nature, but it important to note that this formula applies to all the triangles.

## What is triangle and example?

The definition of a triangle is a shape with three angles and three sides. An example of something in the shape of a triangle is a piece of pizza. Any three-sided or three-cornered figure, area, object, part, etc.

## What are parts of a triangle?

All triangles have three sides and three corners (angles). The point where two sides of a triangle meet is called a vertex. The base of a triangle can be any one of its three sides, but it is usually the bottom one.

## What is Moosh triangle?

: a spherical triangle with one side equal to a quadrant.

## What is downward triangle?

A descending triangle is a bearish chart pattern used in technical analysis that is created by drawing one trend line that connects a series of lower highs and a second horizontal trend line that connects a series of lows.

## What is a polar triangle?

: a spherical triangle formed by the arcs of three great circles each of whose poles is the vertex of a given spherical triangle.

## What is Quadrantal spherical triangle?

A quadrantal spherical triangle is defined to be a spherical triangle in which one of the sides subtends an angle of π/2 radians at the centre of the sphere: on the unit sphere the side has length π/2.

## Who is Father of spherical trigonometry?

Nasīr al-Dīn al-Tūsī

## What is the formula of spherical triangle?

The area of a spherical triangle on a sphere of radius r is equal to the spherical excess times r2. This relationship for the area of a spherical triangle generalizes to convex spherical polygons with the spherical excess being the sum of the angles – (n-2)π, where n is the number of sides of the polygon.

## How do you solve a spherical triangle?

For right spherical triangles, it is customary to set C = 90°. One way of solving for the missing sides and angles of a right spherical triangle is using Napier’s rules. Napier’s rules consist of two parts, and are used in conjunction with a figure called Napier’s circle as shown.
