The 4 angles in a parallelogram add up to 360 degrees.
The 4 interior angles add up to 360 degrees
Look at the parallelogram below. <1 and <3 are each 35 degrees. What is the measurement of <2?
The interior angles of a parallelogram must total 360o and each opposite pair is also equal; these pairs can be any angle except 90o.
We would need to have the parallelogram to answer this question.
