Question

Is it possible to draw the following triangles? Give reasons :
(1) A triangle with two obtuse angles (ii) A triangle with two right angles
(iii) An obtuse angled equilateral triangle (iv) An equilateral triangle with each angle 70°.
​

Answer 1

Answer:

1. no
2. no
3. no
4. no

Explanation:

1. obtuse angle is a triangle with angle more than 90. So 90 + 90 which is not possible
2. 2 right triangles is 90 + 90 so not possible
3. equilateral triangle has each angle 60
4. as above

Answer 2

Answer:

1) No it is not possible.( it is more than 180°)

2) No, absolutely not. ( 2 × 90 = 180°)

3) No, not possible (sum of all is very much greater than 180°)

4) No, not possible. ( it is equal to 210°)
