What kinds of symmetry do an equilateral and an isosceles triangle have?
An equilateral triangle has six symmetries, and an isosceles triangle has two. An isosceles triangle has a single axis of symmetry, the perpendicular bisector of the non-congruent side. This is a reflection symmetry. An equilateral triangle has rotational symmetry as well as reflection symmetry. It is invariant under rotations by 120 degrees.
Can an iscoceles have a 60 degrees angle?
Yes. In this case, the isosceles triangle would more specifically be an equilateral triangle - this can be considered a special case of an isosceles triangle.
A triangle that measures 60 60 60 degrees is a n?
an equilateral triangle
An isosceles triangle is equilateral?
No, isosceles and equilateral are two separate types of triangles. Isosceles triangles have only two congruent sides, while all three sides of an equilateral triangle are congruent.
Could a right triangle ever be equilateral triangle?
No but it is possible for it to be an isosceles triangle with angles of 45, 45 and 90 degrees
An isosceles triangle that is not an equilateral triangle?
It is possible if neither of the angles in the triangle measures to 60 degrees
What type of triangle has an angle that measures 100 degrees and an angle that measures 50 degrees?
A triangle with the third angle that measures 30 degrees.This triangle is not isosceles nor equilateral but has one obtuse angle.
Does an isosceles triangle always have three congruent angles?
Isosceles triangles usually have two congruent sides, but the rule is that they actually have at least two. That means that they can also have a third congruent side. That means they are both equilateral and isosceles*, which I personally think is way too confusing, but that's how it works.Example: A triangle has angles of 60 degrees, 60 degrees, and 60 degrees. It is both isosceles and equilateral.*I think that equilateral triangles are actually a type of isosceles triangle, so that if you're asked on a math test, for example, whether a triangle is scalene, isosceles, or equilateral, you'd say equilateral.No, Isosceles is two equal sides, although an equilateral triangle CAN be an isosceles triangle. And Angles of an isosceles triangle are not known (given) - simply two equal sides.Three, like every other triangle.
Is an isosceles triangle sometimes always or never equilateral?
An isosceles triangle is one that has two sides of the same length and one side different An equilateral triangle is one that has all of its sides of equal length. All of the angles on an equilateral triangle are 60 degrees. A triangle with two sides 4cm and one side 100m would be an isosceles. But an equilateral triangle has all of the sides exactly the same so therefore an isosceles triangle can never ever be an equilateral triangle
How can an isosceles triangle be an equilateral triangle?
An isosceles triangle can never be an equilateral triangle because only 2 of its 3 sides are equal in lenght whereas an equilateral triangle has all 3 of its sides equal in length. But an isosceles triangle can take the shape of a right angle triangle whose interior angles are 90, 45 and 45 degrees.
What kinds of symmetry do an equilateral and an isosceles triangle have?
An equilateral triangle has six symmetries, and an isosceles triangle has two. An isosceles triangle has a single axis of symmetry, the perpendicular bisector of the non-congruent side. This is a reflection symmetry. An equilateral triangle has rotational symmetry as well as reflection symmetry. It is invariant under rotations by 120 degrees.
What type of triangle has an angle that measures 120 degrees and an angle that measures thirty degrees for kids?
It is an obtuse angled isosceles triangle.It is an obtuse angled isosceles triangle.It is an obtuse angled isosceles triangle.It is an obtuse angled isosceles triangle.
Can an iscoceles have a 60 degrees angle?
Yes. In this case, the isosceles triangle would more specifically be an equilateral triangle - this can be considered a special case of an isosceles triangle.
What type of triangle measures 60 degrees?
The 3 interior angles of an equilateral triangle each measures 60 degrees
An isosceles triangle is equilateral?
No, isosceles and equilateral are two separate types of triangles. Isosceles triangles have only two congruent sides, while all three sides of an equilateral triangle are congruent.
Can a right angled triangle sometimes be a equilateral triangle?
No, since an equilateral triangle has three congruent angles of 60 degrees, and a right triangle must have an angle of 90 degrees. However, a right triangle may be an isosceles triangle.
Could a right triangle ever be equilateral triangle?
No but it is possible for it to be an isosceles triangle with angles of 45, 45 and 90 degrees
