Are all rhombuses also rectangles?
No. Rhombuses that are also rectangles are called squares. Rhombuses are parallelograms with 4 equal sides, while rectangles are parallelograms where all the angles are right.
Parallelograms are squares is that sometimes always or never true?
Parallelograms are squares is sometimes true. Squares are parallelograms is always true. Rhomboids are parallelograms is also always true. So not all parallelograms are squares but some are.
How do you find the perpendicular height of a isoceles triangle?
You can find it by using the Pythagorean theorem if you know the side and the base of triangle. In an isosceles triangle the median is also the altitude. The formula is: (The measure of the side length)^2 - (The measure of the one half of the base length )^2 = (The measure of the altitude)^2. Find the square root of the result that you'll have the measure of the altitude.
All quadrilaterals are parallelograms?
Some are, and some are not. A parallelogram is a special kind of quadrilateral ... one in which every side is parallel to the one across from it. So all parallelograms are quadrilaterals, but there are also a lot of other quadrilaterals that are not parallelograms.
Properties shared by all parallelograms are also characteristics of rectangles?
yes
The length of a parallelogram's altitude is also called the what?
height
What can also be called a parallelograms?
A rhombus, rectangle or square.
What shape is a square but not a parelellogram?
No shape is a square but not a parallelogram as all squares are parallelograms: All parallelograms have opposite sides parallel and of equal length, and opposite angles are equal. All squares have opposite sides that are parallel and of equal length, and opposite angles are equal; thus all squares are parallelograms. However, all squares also have all angles equal to 90o and all four sides equal, but some parallelograms have angles not all 90o and/or not all four sides of equal length; thus not all parallelograms are squares.
Are all rhombuses also rectangles?
No. Rhombuses that are also rectangles are called squares. Rhombuses are parallelograms with 4 equal sides, while rectangles are parallelograms where all the angles are right.
What is the area of a trapezoid?
The area of a trapezoid = 1/2 (altitude)(base 1 + base 2) *altitude can also be called the height, or the spacing between the parallel sides. Base 1 is the length of one of the parallel sides, and base 2 is the length of the other parallel side.
What is hypnoxia also called?
altitude sickness
What is altitude sickness also called?
Hypoxia
Is every property of parallelograms also a property of all rectangles?
Yes. All rectangles are also parallelograms, but not all parallelograms are rectangles.
Why will a parallelogram always have a smaller area than a rectangle with the same measurements?
The area of a parallelogram is the length of the 'base' times the altitude. In a rectangle, which is a special case of parallelogram, the altitude is maximum length and also is equal in length to the other side.
Why can a rectangle also be called a parallelogram?
A parallelegram is a kind of shape in which the sets of lines are parallel to each other, such as in the case of a rectangle. Squares and rhombi are also examples of parallelograms. Triangles and circles are examples of shapes that are not parallelograms.
Some parallelograms are squares?
By definition, all squares are parallelograms. Not all parallelograms, however, are squares. All rectangles and rhombuses are also parallelograms.
Are parallelograms also squares?
Parallelograms include squares, but not the other way around.
