Four equilateral triangles make up another equilateral triangle.
An equilateral triangle, has 3 equal sides and 3 equal angles. However, in a regular equilateral triangles, none of these angles are right angles (90 degrees), they are all 60 degrees.
No...
A rectangle.
A square.
No two equilateral triangles do not make a square but two right triangles do.
No. For it to be equilateral it can't be a right triangle.
A rhombus is an equilateral triangle that doesn't have right angles
A rhombus is an equilateral parallelogram that does not have a right angle.
A rectangle by definition has four right angles, so it cannot be equilateral. An equilateral shape has all sides of equal length, which would make it a square or rhombus, but not a rectangle.
It is impossible for a right angled triangle to be equilateral unless it has a double triangle.
right triangle and equilateral triangle both have 3 sides
no. an equilateral triangle is also equiangular, so the angles are 60 degrees each. a right triangle cannot be equilateral
no
It can be scalene or isosceles but not equilateral.
No. In an equilateral triangle, all three angles are the same. Since they are not ninety degrees, you can't have a right triangle that is also an equilateral triangle.
No, an equilateral triangle can't have a right angle, because an equilateral triangle has 3 equal angles of 60 degrees that add up to 180 degrees.
