Question

observe the following angles and answer whether these angles form a triangle or not

1) 30°,60°,80

2) 45°,45°,90°

3) 60°,60°,60°

4) 82°,28°,75°

5) 71°,29°,80°​

Answer 1

Answer:

a triangle must have total sum of angles as 180 degrees

1) 30+60+80=170 degrees

2) 45+45+90=180 degrees

3)60+60+60=180 degrees

4) 82+28+75=185 degrees

5) 71+29+80= 180 degrees.

so here number 2,3 and 5 will form triangles. also number 3 is a equalateral triangle.

Answer 2

Answer:

1. IT IS NOT FORMING A TRIANGLE.

2. IT IS FORMING A TRIANGLE.

3. IT IS FORMING A TRIANGLE.

4. IT IS FORMING A TRIANGLE.

Step-by-step explanation:

We know that sum of all the three angles of a triangle is 180°. so,

1. 30+60+80=170

2. 45+49+90=180

3. 60+60+60=180

4. 71+29+80=180
