If a given parallelogram is a rectangle at least how many of its angles must measure 90?
one
Given parallelogram ABCD describe the relationship between the measure of angle A and the measure of each of the other angles?
The opposite angles are congruent and all add to 360 degrees
How do you find the area of a rectangle with 3 angles given?
A rectangle is, by definition, a parallelogram with four equal angles, all of which equal 90 degrees. If you only know three angles in a rectangle, something is wrong. In order to find the area of a rectangle, you must know its height and length. The area is then found by multiplying these two values together.
What is a quadrilateral with parallel opposites sides?
A parallelogram, or a trapezium, in which only one pair is.
What do you call a rectangle that is slanted?
A slanted rectangle is a parallelogram in the same way that a slanted square is a rhombus.
If a given parallelogram is a rectangle at least how many of its angles must measure 90?
one
To make sure that a given parallelogram is a rectangle at least how many of its angles must measure 90?
You need only 1 90 degree angle.
What parallelogram has 4 right angles 2 pairs of congruent sides?
A rectangle would fit the given description
What is a parallelogram with 4 right angles and 2 pairs of opposite equal sides called?
The description given fits that of a rectangle if not a square

Is every parallelogram's a rectangle?
yes, as long as 2 sides are parallel, its a parallelogram.
What is a quadrilateral with parallel opposites sides?
A parallelogram, or a trapezium, in which only one pair is.
Given parallelogram DEFG If the measure of angle D equals 57. what other angle has a measure of 57?
All you have to remember for this question is that opposite angles in a parallelogram are equal. So if you want to find another angle which is 57, just look at the angle directly opposite.
Given two sides of a rectangle find the angles?
all four angles of any rectangle each equal 90 degrees by definition
What names are given to four sided shape?
quadrilateral, square, parallelogram, rectangle, trapezoid, etc
What is the only parallelogram that can be inscribed in a circle?
Any parallelogram can be inscribed in a circle if the parallelogram is sufficiently small, but only two of the "corners" (a corner is a vertex) of the parallelogram will lie on the circle. But any parallelogram with four right angles (a rectangle or a square) can be inscribed in a circle, and all four of the vertexes will lie on the circumference. So the only parallelogram that can be inscribed in a circle is a rectangle.You'll recall that a parallelogram is a quadrilateral with two pairs of parallel sides. If the interior angles of a parallelogram are right angles, that sets conditions for a special case of a parallelogram called a rectangle. If the sides of a given rectangle are the same length, that rectangle is now a special case of rectangle called a square. Any rectangle (including the special case of the square) can be inscribed inside a circle so all vertexes lie on the circle.If we're interested in a construction project, start by drawing a circle. Then pick any two points on the circle and connect them with a line segment. Next, draw a line segment from each of the original points across the circle, insuring that each line segment is at a right angle to that first line segment. Lastly, connect the two points on the circle where those last two line segments have interesected the circle. You'll find that in every case you try, you'll have constructed a rectangle. And if the line segments all end up the same length, your rectangle will be a square.
