Question

draw a triangle ABC in which BC=6.5cm, angle B=angle C= 60 degree. measure the lenghts of sides AB and AC​

Answer 1

Step-by-step explanation:

In triangle ABC,

angle A + angle B + angle C = 180°

angle A + 60° + 60°= 180°

angle A = 180°-120°

angle A= 60°

so, the triangle is equilateral triangle.

So, AB = BC = AC

AB = AC = 6.5

AB=6.5cm

AC=6.5cm

The length of AB and AC is 6.5cm.

Answer 2

Answer:

First draw a line segment of 6.5cm named BC.

Then, with the help of your protector draw angle B and angle C both measuring 60°.

At the point where the lines of angle B and angle C intersect, name that point as A.

Now you can easily find the length of AB and AC.
