Since a trapezoid is a quadrilateral whose bases are parallel and not congruent, then one of its sides can be perpendicular to its bases (as the shortest distance between two parallel lines). Such a trapezoid is called a right trapezoid.
rhombus, trapezoid
Rhombus. Because a Rhombus has four congruent sides but no right angles.
This is all about the vocabulary. First, quadrilateral, ok so a quadrilateral is a shape with four sides. Next, congruent; congruent basically means equal. So we can say what shape has four equal sides and right angles? Your basic shapes with four sides would be a trapezoid, a parallelogram, a rhombus, a rectangle or a square. The square is the only one of these that fits.
Trapezoid
It can have 2 right angles but normally none unless it is an isosceles trapezoid in which case it will have 2 pairs of congruent base angles
A right trapezoid can have no congruent sides and two right angles.
A quadrilateral has 2 pair of congruent angles and 4 congruent sides. What is the name of the quadrilateral
Since a trapezoid is a quadrilateral whose bases are parallel and not congruent, then one of its sides can be perpendicular to its bases (as the shortest distance between two parallel lines). Such a trapezoid is called a right trapezoid.
trapezoid
rhombus, trapezoid
A trapezoid can't have three right angles. A quadrilateral with three right angles must have a total of four right angles, since a quadrilateral's interior angles add up to 360. 360 - (3*90) = 90, so the fourth angle would have to be right as well. A quadrilateral with four right angles is not a trapezoid; instead it is a rectangle or a square.
Rhombus: A Rhombus has four congruent sides but no right angles.
Rhombus. Because a Rhombus has four congruent sides but no right angles.
trapezoid
trapezoid
Rectangle: A quadrilateral with 4 right angles, diagonals congruent/bisecting, and opposite sides congruent, BUT ADJACENT SIDES ARE NOT CONGRUENT. Rhobus: A quadrilateral with opposite congruent angles, but adjacent angles are Not congruent, perpendicular bisecting diagonals and 4 congruent sides. Square: A quadrilateral that is a rectangle and a square with 4 right angles, diagonals congruet/bisecting that ar perpendicular, and opposites sides congruent.
