Multiple Choice

9. Raj tried to draw a equilateral obtuse triangle but he couldn't. Does this mean that there is no equilateral obtuse triangle or he doesn't know?

• There is no Equilateral Obtuse Triangle, if you want it to be obtuse, it should be an isosceles or a scalene triangle

• There is no Equilateral Triangle because it has equal sides and for obtuse, it should not be equal.

• Raj doesn't know, he needs to think deeper to draw equilateral obtuse triangle

Draw

B. Draw Equilateral Triangle and write how it is a equilateral.
