What is a Triangle?

A Triangle is a type of polygon, which have three sides and three vertices. This is a two-dimensional figure with three straight sides. A triangle is considered a 3-sided polygon. The sum of all the three angles of a triangle is equal to 180°. The triangle is contained in a single plane. Based on its sides and angle measurement, the triangle has six types.

What is a sine law of Triangle ?

In Triangle △ ABC, where a is the side opposite to ∠A, b opposite to ∠B, c opposite to ∠C, and where R is the circumradius, sine law states that a/sinA = b/sinB = c/sinC = 2R
