None, by definition
scalene triangle dose not have any equal sides or angles =)
3 angles
A isosceles triangle can have two equal angles, but an equilateral triangle is actually a special isosceles triangle, so it could also have 3.
all triangles have three corners. An isosceles triangle also has two sides and atwo angles that are equal.
none
Yes it dose.
It has 2 pairs of opposite equal angles which are acute and obtuse.
Yes, it has to in order to be a triangle.
A right-angle triangle will have one right-angle (90 degrees).
Every triangle has 3 interior angles thar add up to 180 degrees
If has anything other than three it's not a triangle...
A triangle with congruent sides and angles is called an equilateral triangle. An equilateral triangle has three lines of symmetry, each one passing through a vertex and the midpoint of the opposite side. These lines divide the triangle into two equal halves, reflecting its symmetrical properties.
