Quick Answer

A quadrangle with one right angle has no special name. It is called a quadrangle or a quadrilateral. Any four-sided shape is a quadrilateral, according to Math Is Fun.

Full Answer

The types of quadrangles that have special names are rectangles, parallelograms, rhombuses, squares, trapezoids and kites. Quadrangles must have interior angles that total 360 degrees. A rectangle has four right angles, and each angle is 90 degrees. A parallelogram does not necessarily have right angles, but opposite angles need to be equal, similar to the rhombus. An isosceles trapezoid has equal angles that come from parallel sides. A kite has equal angles where the two pairs of sides intersect.

  • Q:

    Which quadrangle has at least one right angle?

    A:

    Almost any quadrangle can contain at least one right angle, including trapezoids, kites, rectangles and squares. Rectangles and squares contain four right angles. The opposite sides of rectangles are parallel and of equal length. The opposite sides of squares are also parallel, and each side is the same length.

    What is a linear pair?

    A:

    A linear pair is a geometric term for two intersecting lines with a 180-degree angle. It is also known as a conjecture, or hypothesis, of linear pairs. Linear pairs require unshared sides of the angles to create rays on opposite sides.

    What is the centroid of a right triangle?

    A:

    The centroid of any triangle, right triangles included, is the point where the angle bisectors of all three vertices of a triangle intersect. Given a triangle made from a sufficiently rigid and uniform material, the centroid is the point at which that triangle balances.

  • Q:

    What does a 45-degree angle look like?

    A:

    A 45-degree angle looks like the bisection of a right angle. If one constructs a right angle by drawing one axis horizontally and the other axis vertically, a 45-degree angle is halfway between a flat slope and a vertical slope.
