Answer:
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.

Introduction
The plane figure bounded by three lines, joining three non collinear points, is called a triangle.
There are various types of triangles with unique properties. However, some properties are applicable to all triangles. One such property is the sum of any two sides of a triangle is always greater than the third side of the triangle.
riangle Types:
With regard to their sides, triangles are of three types:
Scalene Triangle: A triangle in which none of the three sides is equal is called a scalene triangle.
Isosceles Triangle: A triangle in which at least two sides are equal is called an isosceles triangle.
In an isosceles triangle, the angles opposite to the congruent sides are congruent.
Also, if two angles of a triangle are equal, then the sides opposite to them are also equal.
In ∆ABC, AB = AC, ∠ABC = ∠ACB
Equilateral Triangle: Equilateral triangle is a unique triangle in which all the angles & all the sides are equal.
In ∆ABC, AB = BC = AC. Then, ∠ABC = ∠BCA = ∠CAB = 60°
