Draw the incircle of the triangle ABC.
Pls ans fast who will ans fast and correct I will mark him as brainliest.​

Answer 1

Construction of Incircle for triangle ABC:

Draw a line segment AB = 5 cm.

Draw a ray BX from B by making an angle of 60°.

Draw an arc on BX from B with radius 6.4 cm.

Name this point as C.

Join A and C.

Draw angle bisectors for angles A and B.

Let the point of intersection be I(incenter).

Now, drop a perpendicular from I such that it meets AB at D.

With I as center and ID as radius, draw the circle(incircle).

This circle touches all three sides of the triangle.

NOTE:

1. You can draw angle bisectors for any two angles.

2. Perpendicular from I can be drawn to any of the three sides.
