Question

Construct ΔABC such that ∠B=100°, BC=6.4 cm, ∠C=50° and construct its incircle.

Answer 1

Answer:

ΔABC & incircle is constructed

Step-by-step explanation:

Step 1 : Draw BC = 6.4 cm using ruler

Step 2 :  Draw angle B = 100° & Angle C  = 50° using protector

Step 3 : Draw intersection of Angle is A

Step 4 : Draw angle of 50° (100/2) at B  & 25° (50/2) at C

Step 5 : intersection of these angles is center of incircle

Step 6 : Using compass Draw two arcs intersecting AB at two position

Step 7 : keeping same length of compass Draw two arcs from intersection points at AB

Step 8 :  join interscetion point of arc with incenter

Step 9 : Using compass take length = (incenter to  (line joining incenter intersecting at AB)

Step 10 : Draw Circle
