Question

construct a triangle ABC in which BC= 5.8 CM Angle B= angle c=30 degree measure AB and ac what do you observe​

Answer 1

Step-by-step explanation:

triangle ABC is an isosceles triangle

Answer 2

It is an isosceles  triangle

Step-by-step explanation:

To construct a traingle ABC

BC = 5.8cm

$\angle B= 30$°

$\angle C= 30$°

steps :

1) Draw a base line BC = 5.8 cm

2) taking B as a center draw an angle of 30°

3) again taking C as a center make an angle of 30°

4) let these angles meet at a point and name it as A

5) now measure AB and AC

Since the base angles are both 30°

using the theorem

sides opposite to equal angles are equal

and when two sides are equal in a triangle

then , its is an isoceles triangle
