Step-by-step explanation:
We have,
AB=7cm.
BC=9cm.
AC=6cm.
∠A,∠B,∠C=?
Construct triangle steps:-
(1):-First draw a line BC=9cm.
(2):-To the compass, draw an arc 7cm. from point B. Then AB=7cm.
(3):- To the compass, draw an arc 6cm. from point C. Then AC=6 cm.
(4):-Meat the pointA to B and C respectively
(5):- measure the angles:
