Answer :
A pentagon has 5 sides. We are looking for a 3-sided shape, which would be a triangle. There are many types of triangles: equilateral (all sides same length, all angles same measurement), isosceles (2 sides same length, 2 angles same measure), scalene (no sides same length, no angles same measure), obtuse (one angle greater than 90°), acute (all angles less than 90°), and right (one angle is 90°).
The triangle shape has 2 fewer sides than a Pentagon.
It is given that in the question that five sides polygon is a pentagon.
It is required that what shape has 2 fewer sides than a pentagon.
What is the triangle?
The triangle can be defined as a three-sided polygon in geometry and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have a pentagon in which the total sides are 5.
The shape has 2 fewer sides than the pentagon ie. a polygon in which there have 3 sides that shape we can call a triangle.
The triangles have various types such as equilateral triangle, right-angle triangle, an obtuse triangle.
Thus, the triangle shape has 2 fewer sides than a Pentagon.
