Question

Draw ∆ABC given AB= 9cm,angle CAB=115° and ∆ABC =40°.Locate its incentre and and also draw the the incircle.​

Answer 1

Step-by-step explanation:

draw the triangle according to the given requirements

the third angle = 180 - (115+40)

= 180° - 155°

= 25°

now draw angular bisectors for all the angles by cutting arcs of equal radii from equal distances from the vertex on the sides

the common p point to all the bisectors is the incentre
