Which of the following triangles are impossible to draw? choose all that apply.

a right scalene triangle
a triangle with sides of 3 inches, 4 inches, and 8 inches
a triangle with angles of 30°, 45°, and 115°
an obtuse equilateral triangle
a triangle with sides of 2 units, 3 units, and 4 units
a triangle with two right angles

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.

I’m pretty sure the answer is a
