Question

Exercise 17C
1. Construct a A ABC such that AB = 7 cm, AC = 6 cm, BC = 9 cm. Measure ZA, ZB and ZC.
2. Construct a A ABC such that AB = BC = AC = 5.8 cm. Name the type of triangle formed and also​

Answer 1

Answer:

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:
