Question

using ruler and compass only construct an isosceles triangle ABC having base equals to 4 cm Vertical angle 45 degree and a median through vertex equal to 2.8cm draw the incircle of the triangle

Answer 1

draw a ray of 4 cm and name point a and b make 90 degree angle on a and o and make 45 degree and then meet arc from 45 degree to point b

Answer 2

Isosceles Triangle ABC is constructed

Step-by-step explanation:

Step1  : Draw a line segment BC = 4 cm using ruler

Step 2 : Using compass taking width slightly less than BC draw arcs on both sides of BC taking B as center

Step 3 : keeping compass width same as in step 2 draw arcs on both sides of BC taking C as center such that it intersect arc drawn in step 2 at P & Q

Step 4 : join P& Q using ruler such that it intersect BC at M

Step 5 : from M take a length of 2.8 cm on line PQ and label other end as A

Step 6 : join AB & AC
