Rectangle
every angle is a right angle (90°)
opposite sides are parallel and of equal length
Triangle

The three internal angles of a triangle always add up to 180 degrees
Trapezoid
Has a pair of opposite sides parallel.
Has four sides
*they both have straight edges
*both quadrilaterals
*Both have 2 sides Parallel
They're both polygons
they all have straight sides and angles
Triangles, Trapezoids, & Rectangles
A triangle is a lot different from the rectangle and the trapezoid. A triangle has a lot less in common with the other two. A rectangle and a trapezoid have a little bit more in common. Because they both have four sides and angle. A triangle is so different from those two because it only has three.
