These triangles are impossible:

a triangle with sides of 3 inches, 4 inches, and 8 inches
(the longest side is greater than the sum of the other 2 sides)

an obtuse equilateral triangle
(all angles in an equilateral triangle are acute)


a triangle with two right angles
The angles of ALL triangles must sum exactly to 180 degrees.  Two right angles sum to 180 degrees so the third angle would have to be zero degrees.

The triangles that will be impossible to draw are those in: Option B, C, D, and F.

What is a Triangle?

A triangle is a 3-sided polygon that has three angles whose sum must be equal to 180°.

In any triangle, sum of any two of its side must be greater than or equal to the third. Thus, a triangle with the following side lengths, 3, 4, and 8 is impossible to draw because: 3 + 4 < 8.

A triangle with angles measuring 30°, 45°, and 115° is impossible to draw because its sum is 190° instead of 180°.

All angles of an equilateral triangle are acute angles, therefore, it is impossible to draw an obtuse equilateral triangle.

A triangle with two right triangles, means that two of its angles equals 180°. If we add the third angle, we would have mroe than 180°.

In summary, the triangles that will be impossible to draw are those in: Option B, C, D, and F.
