4 equal sides and four right angles?
Four equal sides and four right angles is the definition of a square.
What is definition of square?
a regular polygon with 4 equal sides and 4 right angles.
A quadrilateral with equal diagonals and no right angles?
An isosceles trapezoid will have diagonals of equal length but will never contain right angles by definition. A square and rectangle will have diagonals of equal length but will contain 4 right angles. A rhombus and any other parallelogram that does not contain right angles will not have diagonals of equal length.
What is both a rectangle and a rhombus?
nothing fits the definition of rhombus and rectangles becauses the definition for rectangle is : a plane figure with four straight sides and FOUR RIGHT ANGLESbut the definition of rhombus is...a parallelogram with ,OPPOSITE EQUAL ACUTE ANGLES and OPPOSITE EQUAL OBTUSE ANGLES, and four equal sides.
Do sum of 2 complementary angles is equal to 1 right angle?
Yes, the definition of complementary angles is that their sum is 90 degrees. All 90 degree angles are by definition right angles.
Do all rhombuses are parallelograms?
A rhombus is a special parallelogram in its own right inasmuch it has 4 equal sides and 2 diagonals that intersect at 90 degrees
Do all squares have 4 right angles?
Yes, by definition. All squares have 4 right angles and 4 sides of equal length.
What is A quadrilateral with 4 equal sides but no right angles what is it?
Rhombus This is called a rhombus. it can have right angles but doesn't have to. all it has to have is four equal sides. So, a square is under this category. Here is the definition of a rhombus: RHOMBUS: a quadrilateral with four equal sides
Are all isosceles triangles right triangles?
No, only one is and it is known as a 'right isosceles triangle'. By definition an isosceles triangle has two equal sides and two equal angles. If those two equal angles are 45o then the third angle must be 90o.
The angles in a rectangle are all?
... right angles, by definition of a rectangle.... right angles, by definition of a rectangle.... right angles, by definition of a rectangle.... right angles, by definition of a rectangle.
Why is a square both a rhombus and a rectangle?
A square is a rectangle. A square is a rectangle with equal sides. A rectangle Has to have 4 right angles (and only 4 corners). A Square has the same definition (4 right angles, and only 4 corners) but all the sides have to be equal. A square is not a rhombus. A rhombus is a parallelogram with equal sides. A parallelogram has to have 4 sides (2 pairs of equal sides.) The equal sides must be parallel. A rhombus has the same definition (4 sides - 2 pairs of equal sides. The equal sides must be parallel.) but all the sides have to be equal lengths.
Is a square a rhombus because?
A rhombus can be defined in 2 ways: # A quadrilateral with four equal sides, or # A qyuadrilateral with 4 equal sides but no right angles. Both definitions are used. If the definition used is the first of these then a square is a special case of a rhombus. But if it is the second definition then it is not.
