A rectangle is a shape that has more than one right angle. A rectangle has four angles, and two of those angles are always right angles, measuring 90 degrees each. This is a defining characteristic of a rectangle, along with having opposite sides that are equal in length and parallel to each other.
Obtuse. An acute angle is less than 90 degrees, a right angle is 90 degrees, and an obtuse angle is more than 90 degrees.
It is: "angle a is not a right angle" or "angle a is greater than or less than a right angle".
The shape that has 1 acute angle, 1 obtuse angle, and 1 right angle is a scalene triangle. In a scalene triangle, all three angles are different, so it is possible for one angle to be acute (less than 90 degrees), one angle to be obtuse (greater than 90 degrees), and one angle to be a right angle (exactly 90 degrees). This unique combination of angles makes the scalene triangle a versatile geometric shape.
Right angle. An acute angle is less than 90°. An obtuse angle is more than 90°. If it isn't less than or greater than, it must be equal to. Of course a straight angle is more or less an extreme case of an obtuse angle.
An angle smaller than a right angle - is an acute angle. Larger than a right angle, but smaller than 180 degrees is an obtuse angle. Angles between 180 and 360 degrees are reflex angles.
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.
No, if they did the shape would be a square. The angle is more than 90 degrees.
triangle
An obtuse triangle.
True a triangle can only have 1 right angle because it wouldn't be a closed shape with 2
A right angle triangle
It is a triangle
a rectangle
No, a triangle can not have more than one right angle.
No, a triangle can not have more than one right angle.
Depends on the shape. A right triangle has one right angle, a rectangle has 4, an equilateral triangle has none, a circle has no angles. There are polygons with more than 4 right angles, and there is no limit on how many, but those with more than 4 are not convex.
It is impossible for a triangle to have more than one right angle.
