Subject: geometry Can a parallelogram have two 45 degree angles and two 75 degree angles? |
Hi Jenniffeir,
Think about this: If you draw one of the parallelogram's diagonals, you will always get two triangles:
What is the sum of the interior angles of a triangle? So what should the sum of two triangles be? So, what should the interior angles of a parallelogram add to?
