Question

ABC in which AB = 7 cm, AC = 6 cm, BC = 9 cm. measure angle a ,angle b and angle c​

Answer 1

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:

Answer 2

Answer:

$step \: 1$

$draw \: a \: line \: of \: 9 \: cm \: at \: bottom$

$step \: 2$

$take \: a \: compass \: and \: measure \: 7 \: cm \: and \: draw$

$a \: arc \: from \: point \: b$

$step \: 3$

$after \: that \: draw \: another \: arc \: of \: 6 \: cm$

$from \: point \: c$

$step \: 4$

$draw \: a \: line$

$step \: 5$

$at \: last \: measure \: all \: the \: angles$

$with \: the \: help \: of \: compass$
