What makes a rectangle a special kind of parallelogram?
It is a right angled parallelogram.
What type of polygon is rectangle?
A right angled parallelogram.
How many acute angles are there in a parallelagram?
A parallelogram has 0 or 2 acute angles. If the parallelogram happens to have four right-angled corners, it is still a parallelogram (and a rectangle), but no acute angles.
Is the area of a rectangle and paralleograme having equal length of sides equal?
Yes, but only if the parallelogram has right angled vertices.
How many names are possible for a rectangle?
Some of them are: oblong, quadrilateral, right angled parallelogram, a shape with opposite parallel sides and then their is the golden rectangle.
What makes a rectangle a special kind of parallelogram?
It is a right angled parallelogram.
What type of polygon is rectangle?
A right angled parallelogram.
How do you use two right angled triangles to make a parallelogram?
If they are congruent right angle triangles then just join them together side by side to form a parallelogram.
If a parallelogram has a right angle then it is a rectangle?
No because it could be a right angled trapezoid. A rectangle must have four right angles. Yes, a parallelogram with a right angle is always a rectangle. In fact, in my geometry book, some 55 years ago such was the definition of rectangle. A parallelogram with one right angle will always have four right angles. The right angled trapezoids that are not rectangles are not parallelograms.
How many acute angles are there in a parallelagram?
A parallelogram has 0 or 2 acute angles. If the parallelogram happens to have four right-angled corners, it is still a parallelogram (and a rectangle), but no acute angles.
What is a list of quadrilateral that have right angled vertices except square and rectangle?
You can have a trapezium, a kite or an arrowhead with right angled vertices, as well as a completely irregular quadrilateral. In fact, any kind of quadrilateral other than a parallelogram (or rhombus) can have a right angled vertex.
Is the area of a rectangle and paralleograme having equal length of sides equal?
Yes, but only if the parallelogram has right angled vertices.
What is an oblique-angled parallelogram with four equal sides?
A Rhomb

What is a quandrangle that has at least 1 right angle?
A right angled quadrangle! It can be a trapezium, kite, arrowhead, rectangle or square. It cannot be a parallelogram or rhombus - other than a rectangle or square respectively.
What are rectangles that are not squares I need 4.?
A rectangle can be any four-sided plane figure with four right angles, including a four-sided polygon, a quadrilateral, a rhombus, a quadrangle, and a right-angled parallelogram,
What is a good definition for the word rhombus?
A rhombus is an oblique-angled equilateral parallelogram, but not a square. Explanation: Oblique-angled means that there can be no perpendicular angles like in a square.
