Area of a trapezoid: 0.5*(sum of its parallel sides)*height
acute, obuse, or right angles
quadilateral (four sides) of any lengths, as long as two of them are parallell.
A perpendicular edge is a side of a plane shape that is at right angles (90 degrees) to another edge.
1/16/2013 10:06 pm New York State I'm 5 grade Dear Friend, the math i just learn about shape , but i can explore the answer for you . The different between parallelogram and trapezoid is the parallelogram had 2 pair of parallel ,but trapezoid had 1 pair parallel. It different is it had different how many pair are they. The Parallelogram and trapezoid are the same because it also a parallel line in there shape From, Angelina Nguyen

A trapezoid is a quadrilateral with exactly one pair of parallel sides. The non-parallel sides are typically of different lengths, causing the angles connected to those sides to be unequal. Thus, in a trapezoid, the non-parallel angles are not equal.
Yes . Some might have acute angles . Most likely right angles .

A rectangle is classed as a 4 sided quadrilateral in math.
A pentagon has five angles, and all of them are less than a right angle. So, the answer is five angles less than a right angle. Math doesn't have to be a Pentagon-level secret, honey.
That is a stupid question they are not related at all that is completely retarted you are a moron go read a math book
You have to be in eight grade to do eight grade math. Except if you are very smart.
3rd grade math
