How many lines of symmetry are in a triangle?
The number of lines of symmetry of a triangle depends upon the kind of triangle it is:A scalene triangle with no side lengths equal has no lines of symmetry;An isosceles triangle with two sides equal has 1 line of symmetry that bisects the angle between the two equal sides;An equilateral triangle with all three sides equal has three lines of symmetry - the three lines are the bisectors of the three angles.A right triangle is a triangle where one angle is 90°. A right triangle is either a scalene triangle with no lines of symmetry or an isosceles triangle (where the legs are of equal length) with one line of symmetry which bisects the 90° angle.No triangle can have exactly 2 lines of symmetry.
How many lines of symmetry are in a regular triangle?
If you're referring to an equilateral triangle, a triangle in which all three sides are the same length, then there are three lines of symmetry.
What triangle has 2 lines of symmetry?
An equilateral triangle will have three lines of symmetry. Others will have one (or none). There is no triangle with only two.
What figure has exactly three lines of symmetry?
An equilateral triangle has exactly three lines of symmetry. It is the only shape that contains exactly three lines of symmetry.
What is a triangle that has no lines of symmetry?
A triangle having each of its three sides of different lengths is a scalene triangle. That would also mean there are no lines of symmetry.
