might be an equilateral triangle. isosceles triangle or a right angled triangle :)
If two lines intersect in the same plane to form a right triangle what can be concluded?
trtdrtdrtd
Can a triangle have two parallel angles?
In two dimensions, lines can be parallel, angles cannot. So no plane shape has parallel angles.
What are The measure of an exterior angle of a triangle is greater than the sum of the measures of the two opposite interior angles?
It is an indication of an error, or the fact that the triangle is not in the Euclidean plane but on a convex surface.

Does a triangle have sides that are perpendicular?
No, not in general. Only a right triangle has two sides which are perpendicular.
How many edges and faces does a triangle have?
An edge is the set of points where two (or more) planes meet. Since a triangle must be in just one plane, it cannot have any edges. It has one face, which is part of the plane containing the triangle.
