It is: "angle a is not a right angle" or "angle a is greater than or less than a right angle".
A right angle measures 90 degrees
right-angle triangle has at least one right angle .
There are 90o in a right angle. A right angle is one-quarter of a full circle i.e. 360o.
an angle with a acute and right angle
yes it does
A rhombus. (Looks like a diamond.)
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.
Its easy to cut a diamond if you know how to do it but its very hard to get the angle right, but they're the hardest substance on the planet.
* Right triangle * square * rectangleA Right triangle, a parallelogram, a rectangle, a rhombus, a square and a diamond.
a diamond
It could be a right trapezium, a kite (diamond), or just a general quadrilateral which meets these requirements.It could be a right trapezium, a kite (diamond), or just a general quadrilateral which meets these requirements.It could be a right trapezium, a kite (diamond), or just a general quadrilateral which meets these requirements.It could be a right trapezium, a kite (diamond), or just a general quadrilateral which meets these requirements.
A standard diamond shaped kite may not have a right-angle, but kites come in many sizes and shapes. For example, a box kite will have several right-angles. Whereas the rather fancy dragon and animal shaped kites on public display are usually right-angle free.

a right angle is a right angle
Look at a diamond symbol in a pack of cards. The top and bottom vertices are usually acute angles.
Because a right angle is a right angle.
