None
No triangle has 2 obtuse angles
a triangle has no parrallel lines. it will only be parrallel if it is a quadrilateral
No, An equilateral triangle has 3 congruent angles, an isosceles triangle has 2 congruent angles, a scalene triangle has no congruent angles.
does a equilateral triangle have 2 interior angles
Isosceles triangle.
no because if an scalene triangle had 2 congruent angles it wouldn't be a scalene it would be a isosceles triangle because an isosceles triangle is the only triangle with 2 congruent angles
An isosceles triangle has 2 equal sides and 2 equal angles.
If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)
Not normally because it would be an isosceles triangle that has 2 congruent angles
isoceles triangle
Isosceles triangle.
