How much rotational symmetry does triangle have?
It depends on the type of triangle. A scalene triangle (no equal sides) has no rotational symmetry. An isosceles triangle (2 equal sides) has rotational symmetry order 2. An equilateral triangle (3 equal sides) has rotational symmetry order 3. The order of rotational symmetry is how many time a shape will fit over itself during one complete rotation.
How do you describe triangles by the sides?
Scalene Triangle- a triangle with no congruent sides Isosceles Triangle- a triangle with two congruent sides Equilateral Triangle- a triangle with three congruent sides
What type of triangle's sides have all nine sides?
A triangle can have only three sides. No triangle can have 9 sides!
What kind of triangle has no 2 sides equal?
Scalene Triangle: a triangle with no two sides equalIsosceles Triangle: a triangle with two sides equalEquilateral Triangle: a triangle with all sides equalRight Triangle: A triangle with two 'legs' vertex creates a 90o angle.
What triangle has at least two sides that are parallel?
A triangle cannot have two parallel sides. In order for a figure to be a triangle, it must be a closed figure with three sides and three angles. If two of the sides were parallel, there is no way the figure could be closed by only one other line.
What is a triangle with at least two congurent sides?
A triangle with two congruent sides is an isosceles triangle, and a triangle with three congruent sides is an equilateral triangle.
Which measurements could be the lenghts of the sides of a triangle 5cm2cm7cm?
No the given measurements would not make a triangle because in order to construct a triangle the sum of its smallest sides must be greater than its longest side.
What triangle has no congruent sides?
A scalene triangle has no congruent sides. An equilateral has all equal sides, and an isosceles triangle has two of three sides equal.
How is the equilateral triangle different from the isosceles triangle and scalene triangle?
They all have 3 sides but an equilateral triangle has 3 equal sides, an isosceles triangle has 2 equal sides and a scalene triangle has no equal sides.
Is sides 2 and 4 and 8 can form a triangle?
No because in order to construct a triangle the sum of its 2 smaller sides must be greater than its longest side.
Can sides 9 4 and 15 form a triangle?
No because in order to construct a triangle the sum of its 2 smallest sides must be greater than its longest side
How many sides are there on a triangle?
A triangle has three sides.
