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.
How do you draw a quadrilateral with one reflex angle?
Well, honey, drawing a quadrilateral with one reflex angle is as easy as pie. Just sketch out four sides, make sure one angle is greater than 180 degrees, and voilà, you've got yourself a quadrilateral with a reflex angle. Just remember, it may look a little wonky, but hey, math isn't always pretty.
How do you find angles of a parallelogram?
To find the angles of a parallelogram, you have to know at least one angle (although it could be an interior or an exterior angle). There are several facts about all parallelograms:the sum of the interior angles is 360˚ (true for all quadrilaterals)opposite angles are congruent (angles that are diagonal in parallelograms have the same measure)consecutive angles are supplementary (angles that are connected by a single side add up to 180˚)If you know any of the interior angles, you can use a combination of the above rules to find the rest. If all you know is an exterior angle, then use the fact that an interior angle and its exterior angle are supplementary (because they are a linear pair--they make a line) to find the measure of the interior angle; then use the rules given above.
A triangle and a parallelogram can be combined to make a?
a triange and a parallelogram can be combined to make a?
What angle with a measure of 92 degrees?
Obtuse angle (here is the formula) -: 90° = Right angle and if you don't know the obtuse angle is more than 90° so adding 2 will make it an obtuse angle.
What measure of a will make this quadrilateral a parallelogram?
123
How do you make a quadrilateral?
A quadrilateral is a parallelogram with four sides. For example: square, rectangle, parallelogram, trapezoid, rhombus, diamond...
What type of angle is not a parallelogram?
The questions doesn't make sense. An angle isn't a parallelogram. Parallelograms are types of shapes while an angle are to rays.
What measure of angle a will make this quadrilateral a parallelogram 10x-23 7x 1?

Can you put two congruent triangles together to make a quadrilateral that is not a parallelogram?
Yes. They can form a kite.
Does a parallelogram has right angles?
no only 2acute angle n 2 obtuse angle A right angle would make it a rectangle - still a parallelogram but a special one with a specific name.
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 angle does the height intersect with the base of a parallelogram?
The height is a perpendicular angle from the base. The sides of the parallelogram are slanted tho and this will vary for every parallelogram. To find the height you typically make a triangle with one of the slanted sides.
Is a right angle a quadrilateral?
No... a quadrilateral is a figure of 4 sides. Trapzoid, square, diamond.... get the picture? A right angle is an angle. It is formed by two lines intersecting. They don't even necessarily make a shape.
How does a quadrilateral with a 200 degree angle look like?
make a v shape
How many degrees altogether do all the angle of a quadrilateral make?
The 4 interior angles of any quadrilateral add up to 360 degrees
How do you draw a quadrilateral with one reflex angle?
Well, honey, drawing a quadrilateral with one reflex angle is as easy as pie. Just sketch out four sides, make sure one angle is greater than 180 degrees, and voilà, you've got yourself a quadrilateral with a reflex angle.
