well you can just talk a steamy poo on that homework your doing right know and go out and party cause this sight sucks any way
Is a rhombus.
If all adjacent angles are congruent, it can only be a rectangle (or square).
The quadrilaterals with all angles congruent are rectangles and squares. They are the only quadrilaterals in which all four angles are right angles.
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.
Yes, if a quadrilateral has 4 congruent sides and 4 congruent angles, it is a square. Since it is a square, all angles are 90o. Since there are no angles above 180o, it is convex.
Yes. It is still a quadrilateral as long as it still has four sides, and they can be congruent if all of the sides are equal. It does not mean that All of the angles have to be right.
No, a parallelogram with 4 equal sides would not have 4 congruent angles, only two.
Yes. It would be a rhombus.
A square would fit the given description.
An ireggular square has sides all the same lenght but all the angles are not congruent
A rectangle is a quadrilateral with four sides. All angles are right angles, the diagonals are congruent, and the opposite sides are all equal. A rhombus (diamond) is a quadrilateral with congruent daigonals and equal angles.
I can't find a name for it but an example would be a trapezoid. Some might have congruent angles but not all do.
A quadrilateral is ANY closed figure with 4 sides. Therefore, it also has 4 angles - any of which may, or may not, be congruent. About the only general statement about angles that applies to all quadrilaterals is that the sum of the angles is 360 degrees. By the way, it is possible for a quadrilateral to have 3 congruent angles, and the fourth angle not be congruent with the other 3.
A Rhombus is:A quadrilateralAll sides equalOpposite sides parallelA Rhombus is a quadrilateral, therefore its interior angles sum to 360°If all the interior angles are congruent they are all 360° ÷ 4 = 90°Thus a Rhombus will 4 congruent angles is:A quadrilateralAll sides equalOpposite sides parallelAll angles equal (to 90°)This is the the definition of a Square. A Square is a "special" Rhombus with all angles equal.
Rectangles;all angles equal 90 degrees
RectangleA rectangle has 4 congruent angles, but two pairs of congruent sides instead of all sides being congruent.
