To find the number of angles in a parallelogram, we first need to understand what a parallelogram is.
A parallelogram is a four-sided polygon with opposite sides that are parallel and equal in length. It also has opposite angles that are equal. Since all the sides in a parallelogram are parallel, the opposite angles are also equal.
Now, let's determine the number of angles in a parallelogram. Since a parallelogram has four sides, we know it must have four angles. Additionally, since opposite angles in a parallelogram are equal, we can conclude that each pair of opposite angles are the same. Therefore, we can divide the total number of angles in a parallelogram by 2 to find the number of unique angles.
So, a parallelogram has four angles, but since opposite angles are equal, it has two unique angles.
In comparison, we know that a triangle has three angles since it has three sides. So, a parallelogram has half as many angles as a triangle.
