Question

Draw a triangle ABC with side BC =6.5cm, angle B=30, angle A=105 . Then construct another traingle whose sides are 3/4 times the corresponding sides of the triangle ABC.

Answer 1

Answer:

Δ ABC is constructed

Step-by-step explanation:

BC =6.5cm,∠B=30°, ∠A=105°

∠A + ∠B + ∠C = 180°

=> 105° + 30° + ∠C = 180°

=> ∠C = 45°

Step 1 : Draw line segment BC = 6.5 cm using ruler

Step 2 : Draw an angle of 30° at  B using protector

Step 3 : Draw an angle of 45° at  C using protector

Step 4 : Find intersection point A  of both angles

Step 5 : Join AB & AC

Δ ABC is constructed

Find Bisector of BC  at point D

then find bisector of CD at E

now BE = (3/4)BC

Now in step 1  , take length = BE

and repeat the step from 2 to 5

Answer 2

Step-by-step explanation:

draw bc =6.5,angle b=30 dgree, angle a= 105 degree
