Question

Construct triangle ABC BC=6.5cm angle C=60 AB-AC = 2.5 cm.​

Answer 1

Answer:

Step 1. Draw a line segment AB=7 cm

Step 2. At a point, A draw an angle of 60

∘

and extend the ray.

Step 3. Taking B as center and radius 6.5 cm draw an arc

intersecting the ray at C.

Step 4.Join B to C

Now measure AC using a ruler.

AC=5.7 cm

Answer 2

Step-by-step explanation:

Given that :In ∆ABC BC=6.5cm angle C=60 AB-AC = 2.5 cm.

To find: Construct triangle ABC

Solution:

Steps of construction:

1. Draw a base line BC= 6.5 cm
2. At C draw an angle of 60°,with the help of protector or compass an draw angle ray in downward direction as shown in attachment .
3. Measure the length 2.5 cm on downward ray of 60° angle and mark that point X.
4. Join BX and draw the perpendicular bisector of BX with the help of compass.
5. The bisector of BX join CY at a point,mark that point A.
6. Join B to A.
7. Construction of ∆ABC has been done.

Verification:

Measure AB and AC.

*If the construction has been done using proper scale.

here in my construction

AB= 5.8 cm

AC= 3.3 cm

AB-AC= 5.8-3.3= 2.5 cm

which is desired.

Hope it helps you.
