What are isosceles triangels?
Isosceles triangles are triangles in which two of the three sides have different lengths.
What are the properties of scalene triangles?
* All sides are different lengths *
A triangle with all different sides?
Scalene triangles have no congruent side lengths.
What type of triangle has sides that are always all of different lengths?
Scalene triangles
What things are scalene triangles?
Scalene triangles are polygons like all triangles. The lengths of the sides of scalene triangle are all different.
Do triangles always have three lines of symmetry?
No, scalene triangles, which have sides of different lengths, have none. Isosceles triangles, with only two sides the same, only have one.
What are triangle with three sides of different lengths?
Scalene Triangle. Isoceles triangles have 2 equal lengths (Trick: 2 eyes), Equallateral triangles have all equal sides. Self explanatory...
Are all triangles equilateral?
No.Equilateral triangles must have equal angles (all 60 degrees) and equal length sides; there are also:Isosceles triangles which have two equal angles and two equal sides;Scalene triangles which have all three sides, and hence all three angles, of different lengths;Right angled triangles (which can have all sides of different lengths, or two sides of equal length) have (as the name suggests) one right angle. This means Pythagoras and the trigonometric ratios can be used on its side lengths.
What is the different between all of the 4 triangles?
Equilateral triangles have 3 sides all of the same lengths and the three angles are equal (60°). Isoceles triangles have two sides of equal length with both of those side angles being equal while the other is different. Scalane triangles have all sides of different lengths and different angles. Right angled triangles have one angle of 90° and the other two will total 90°.
Are some scalene triangles also isosceles triangles?
Scalene triangles those triangles in which all the sides are of different lengths, but in isosceles triangles two sides of the triangle are equal in length. Therefore, no scalene triangle can ever be isosceles.
Do equilateral triangles have sides?
No but their 3 sides are equal in lengths
Do right triangles and hexagons both have all sides of equal lengths?
Only when they are equilateral triangles and regular hexagons that both will have sides of equal lengths.
