There is no special name for such a shape.
It could be a kite, an arrowhead or an irregular quadrilateral with a right angle - which has no specific name.
A general quadrilateral or a kite.
Not possible... The internal angles of a quadrilateral always total 360. If you MUST have an angle of 90 degrees - the remaining angles must total 270. At least one of the remaining angles will always be obtuse.
A Right Triangle or sometimes called a Right-angled Triangle has one angle = 90 degrees
This is an arrowhead quadrilateral.
There is no special name for such a shape.
a rectangle
A square.
it is a somehow slanted triangle.
It could be a kite, an arrowhead or an irregular quadrilateral with a right angle - which has no specific name.
It can be an irregular quadrilateral, or a kite or arrowhead.
A four-sided shape with one right angle is a quadrilateral. There is no more specific term, unless it has more than one right angle or has equal sides.
Four SIdes
If a shape has four sides and you know that it has one right angle, yet you do not know anything else about the shape, then the most specific geometric term you can assign to the shape is "quadrilateral". Unless you know about the other angles and side lengths, nothing more can be said.
It could be a kite, a trapezium, a chevron or just an irregular quadrilateral with one right angle and no specific name.
Yes I had a question on my maths test asking me to draw a quadrilateral with one right angle, so yeah, a quadrilateral can have exactly one right angle lol But i havent got a clue how to draw one :S
there is no unique name for a shape like that as it would just be called an irregular quadrilateral
