Answer 1

in this chapter tere is a study of triangles formula,structure and properties.

Answer 2

hey your answer is here there is the constructions of triangle there is geometrical Constructions triangle whose three sides are given and next exercise constructions of triangle whose two sides and angle between them is given like steps of Constructions first step draw a line segment second step at a point with the help of ruler triangle DBC you do like this type and in third exercise constructions of right angle the hypotenuse and other side is given and next exercise constructions of a triangle whose two side and an angle opposite 1 of given and now we draw difficult Triangles of Constructions like a Kishan constructions of triangle ABC in which BC = 2000 = 2 degree and Angle 8cm now some important points like if two side and their 1 opposite acute angle is given soc triangle can be made but the final triangle cannot be decided in contain two conditions therefore condition is not clear second. If all three sides are given so the construction of triangle is not possible third point in right angle triangle hypotenuse and one side is always equal
