no, only equilateral triangles have 3 lines of symmetry
Yes, any polygon can be composed using only triangles.
No, scalene triangles, which have sides of different lengths, have none. Isosceles triangles, with only two sides the same, only have one.
11
because there are only THREE sides/ray.
Draw one square. Join the midpoint of each side to the midpoint of the adjacent sides. The resulting figure meets the requirements.
Triangles, Circles, Ellipses Only triangle if you only want polygons.
No, isosceles triangles only have one. ■
Right triangles can have only one line of symmetry. Only right triangles with two 45 degree angles can have a line of symmetry.
Yes
I think it is either a right triangle, square, pentagon, or rectangle.
Perpendicular. Bt ONLY right triangles contain perpendicular lines.
