Question

5. Construct a AABC in which BC = 5 cm, AB = 3.8 cm and AC = 2.6 cm,
Bisect the largest angle of this triangle.
ARC in which BC = 4,8 cm, ZB = 45° an​

Answer 1

Answer:

Step of Construction:

Construct line segment AC=2.5 cm

Considering A as centre and radius 3.8 cm construct an arc

Considering C as centre and radius 5 cm construct an arc which intersects the previous arc at the point B

Join the point AB and BC

So we get △ABC

From the figure we know that BC is the largest side of the triangle

BC=5 cm

We know that ∠A is the largest angle

Considering A as centre and any radius, construct and arc which intersects AB at point P and AC at point Q

Considering P as centre and radius more than half of PQ, construct an arc

Considering Q as centre and same radius, construct an arc intersecting the previous arc at the point R

Join AR and extend it

Therefore, ∠A is bisected by the ray AR.

Answer 2

first one

BC 5cm,AB 3.8 cm AC 2.6 cm

5+3.8+2.6.

The ans is11.4
