Question

Need help.please on number one

Answer 1

6 sides because it's a triangle and 2 angles

Answer 2

The answer is 12 including both sides and angles.

When you cut a square piece of paper from one point to the opposite point it should make two triangles.

Thus each triangle has 3 sides and 3 angles so two triangles has 6 angles and 6 sides

So 12, sides and angles added together.
