What angles does a heptagon have obtuse or reflex?
Obtuse
How do you draw a trapezoid with 3 right angles?
It would be impossible. A trapezoid can't have three right angles. It would just make a rectangle.
How do you draw a quadrilateral that has four right angles?
Draw a square
Draw a quadrangle that has 2 pairs of parallel sides and no right angles?
Draw a parallelagram this has the opposite sides parallel and no right angles
Can you draw a triangle with three different angles?
Yes, as long as they all add up to 180 degrees. A triangle cannot have 2 right angles. A triangle with three different angles is called a scalene triangle.
Can you draw a trapezoid with three right angles?
no
Is it possible to draw a triangle with three right angles on a sphere?
It is impossible to have a triangle with 3 right angles. It is possible to draw a triangle with three right angles on the surface of a sphere: www.metacafe.com/watch/769025/270_degree_triangle_yes_3_right_angles
Can you draw a quadrilateral with three angles bigger than a right angles?
Yes.
Why can you not draw a trapezoid with three right angles?
The sum of all four angles is 360 degrees. If three of the angles were right angles then the fourth would have to be a right angle. You would then have a rectangle or a square, but not a trapezium.
What angles does a heptagon have obtuse or reflex?
Obtuse
Can you draw a trapezoid with three right angles why?
No, because then it would be a rectangle.
Can you draw a quadrilateral that has three right angles?
The sum of the interior angles of a quadrilateral is 360 degrees. If three of the angles are right angles, that is, of 90 degrees each, the the fourth must be 90 degrees. So you can have a quadrilateral with three right angles but its fourth angle will also be a right angle. So exactly 3 right angles is not possible.
Is it possible to draw an equiangular right triangle?
No, it is impossible to draw an equiangular right triangle. An equiangular triangle has three 60o angles. A right triangle has one 90o angle, and two 45o angles.
How do you draw a trapezoid with 3 right angles?
It would be impossible. A trapezoid can't have three right angles. It would just make a rectangle.
What shape has three right angles?
I will rephrase your question as "What shape has only three right angles?" A shape is a 2D drawing that encloses some space. The sum of the angles must exceed 270 degrees. A rectangle is out of the question as it has four right angles. But a 5 sided shape with unequal sides (irregular pentagon) or higher number of sides is fine. I wish Wikipedia would let draw on these answers, because I could draw hundreds of shapes with three right angles. When we talk of shapes, the most regular shapes come to mind, triangles, squares, pentagons, etc. But you did not spcify that my shape had to have straight sides. Imagine, for example, a circle which I will break at three places and insert right angles. Weird, but it does have three right angles. Do the right angles have to face in towards the center? I could even draw a more bizarre shape with with three right angles facing out, connected by curved lines.
How do angles of heptagon add up too 900?
If you select one vertex of a heptagon and draw diagonals to all other vertices, you will divide the heptagon into 5 triangles such that the interior angles of the heptagon add up to the same sum as the interior angles of the five triangles.Now the sum of the interior angles of one triangle is 180 degrees. So for 5 triangles you get 5*180 = 900 degrees.In general, the interior angles of a polygon with n vertices is (n - 2)*180 degrees.
How do you draw a quadrilateral that has four right angles?
Draw a square
