Question

Draw a triangle ABC in which BC=8cm, angle B=50 degree and angle A=50 degree. Also bisect angle A and angle C​

Answer 1

Answer:

=8 cm , \angle B=50∠B=50 degree and \angle A=50∠A=50

We know for a \bigtriangleup ABC△ABC ,

\angle A+\angle B+\angle C=180∠A+∠B+∠C=180

⇒\angle C=180-\angle A-\angle B∠C=180−∠A−∠B

⇒\angle C=180-50-50∠C=180−50−50 (By plug the values)

⇒\angle C=80∠C=80

Answer 2

Answer:

TO FIND THE ANGLE C:

As we will know that the sum of interior angle of triangle is 180 degree.

Angle A = 50 degree

Angle B = 50 degree

Angle C = ?

Angle B + Angle A + Angle C = 180 degree

50 degree + 50 degree + Angle C = 180 degree

100 degree + Angle C = 180 degree

Angle C = ( 180 - 100 ) degree

Angle C = 80 degree

STEPS OF CONSTRUCTION :

1. First we draw a rough figure of triangle.

2. Then, we draw a line segment BC of 8cm length.

3. At point B, we construct 50 degree angle.

4. In this step we will do same thing that at point C, we construct 50 degree angle.

5. By meeting angle B and angle C the angle A is automatically made.

6. Therefore, the triangle ABC is constructed.

And the angle A and angle C is bisect.

In last I want to telling something that the triangle ABC is ISOCELES TRIANGLE.
