Question

construct triangle ABC in which BC=4.5, angle B= 120 AB= 5 through a draw a line line parallel to bc write steps​

Answer 1

Answer:

Since it is a parallelogram, length of opposite sides are equal.

therefore,

AD=4.5cm

CD=6.5cm

Step-by-step explanation:

Step-by-step explanation:

Step 1 : Draw a line AB  = 6.5 cm using rule

Step 2 : Draw angle of 60° at B on AB using protector

Step 3 : Take a length of 4.5 cm from B on angle drawn in step 2 and label it C

to Draw a line passing through C parallel to BA

Step 4 : Draw an angle of (180° - 60° = 120°) at C on BC

to Draw a line passing through A parallel to BC

Step 5 : Draw an angle of (180° - 60° = 120°) at A on AB such that it intersect angle drawn in step 4 at D

AD = BC = 4.5 cm

CD = AB = 6.5 cm
