Why does a scalene triangle have no lines of symmetry?
The definition of the word "scalene" is a triangle having three sides of different lengths.The mathematical definition of "symmetry" is an exact reflection of form on opposite sides of a dividing line/plane.Therefore, by definition, no lines of symmetry exist in a scalene triangle.
How many sides does an scalene triangle have?
By definition, a triangle has three sides.
The isosceles triangle theorem states that if two sides of a triangle are congruent then the opposite those sides are?
The isosceles triangle theorem states that if two sides of a triangle are congruent, then the angles opposite those sides are congruent.
How many sides does a scalene triangle have?
3 sides - such is the definition of triangle. Every triangle of any type has three sides.
What is the Isosceles Triangle Theorem in Geometry?
The Isosceles Triangle Theorem:If two sides of a triangle are congruent, then the angles opposite the sides are congruent.The Converse of Isosceles Triangle Theorem:If two angles of a triangle are congruent, then the sides opposite those angles are congruent.
