Three
A triangle has three sides or edges.
there are no curved edges on any triangle.
There are three straight edges in a triangle.
An isosceles triangle consist of 3 straight lines 2 of which are equal in length
there are three angles on an isosceles triangle
No. An isosceles right triangle is a special case. There are many right triangles which are not isosceles.
because an isosceles triangle or any kind of triangle is 180 degrees.
Isosceles triangle have two equal angles2
A flat (2D) shape triangle has 3 straight edges. A triangular pyramid has 6 straight edges. A square pyramid has 8 straight edges. (Note, some vertical edges have already been counted as you move from one face to the next.)
An isosceles triangle has only 1 line of symmetry.
In an isosceles triangle, two of the angles are the same.
An isosceles triangle has no parallel sides but it does have two equal sides
