no they can be isosceles but not equilateral
yes a isosceles triangle has a right,obtuse and acute angle.
acute, isosceles right, obtuse, and equilateral
Equilateral and Isosceles Triangles
They are: right angle, isosceles and equilateral triangles There are also scalene and obtuse triangles
Obtuse triangles can also be scalene if none of the sides are of equal length. Otherwise, it is an isosceles triangle.
There are three different types of triangles; equilateral, isosceles, and obtuse triangles.
false
Triangles without right angles are:- Scalene triangles Obtuse triangles Isosceles triangles Equilateral triangles
The third angle can be obtuse, eg 40, 40 and 100
infinite amounts of isosceles triangles as any length can be any size, just in the same ratio to each other.
