Answer 2

A three sided polygon is called​ triangle.

Step-by-step explanation:

• A triangle is a polygon with three sides. Triangles come in a variety of shapes and sizes, including the following:
• Equilateral — all sides are the same length and all internal angles are 60 degrees.
• Isosceles - has two equal sides and a differing length third side. Two of the internal angles are exactly the same.
• Scalene has three distinct sides and three internal angles.

• Internal angles can also be used to describe triangles (see our page on Angles for more about naming angles). A triangle's internal angles must always add up to 180°.
• Acute (or acute-angled) triangle refers to a triangle having solely acute internal angles. Obtuse (obtuse-angled) means having one obtuse angle and two acute angles, while right-angled means having only one obtuse angle.
