Its a Right Triangle * * * * * No, a right triangle has only one pair of perpendicular lines. One possible answer is a kite, with right angles at the left and right extremes. There would be an obtuse apex and an acute bottom (or the other way around).

No, trapezoids do not have right angles. A trapezoid is a quadrilateral with only one pair of parallel sides. The other two non-parallel sides can be of different lengths and angles.

A prism has two parallel and congruent bases in the shape of polygons. Example - a cereal box (is rectangular prism). The top and bottom are rectangles(a polygon). They are the same size and shape (congruent) and also parallel. A cube (think of six sided dice) is a special rectangular prism. Imagine a a box where the top and bottom are triangles (of the shape size and shape). This is called a triangular prism.

Like this -> Vertical would be top to bottom, which goes from 0 to 180 degrees Horizontal would be left to right, which goes from 90 to 270 degrees Lines are parallel when their angles and orientations are the same. Therefore you can also have diagonal (corner to corner) parallel lines as well.

Yes, the top and bottom are parallel to each other.

A trapezium (or trapezoid in North America) does not necessarily have any right angles. The only requirement is that it is a quadrilateral (4 sided polygon) with one pair of parallel sides. If one of the sides is perpendicular to the bottom base, then it is also perpendicular to the top (so 2 right angles). If the other side is also perpendicular to the bottom base then it will be perpendicular to the top base as well, then it is a rectangle, with four right angles.

I, the top and bottoms lines are parallel, but the vertical line is perpendicular to the top and bottom lines.

They are always identical angles unless the bottom and top lines are not parallel!!!!

Think of your regular trapezoid (half a hexagon). Now cut it in half with a line perpendicular to the top and bottom. You can see the right angles along one side. The top and bottom lines are parallel. The seond angle on the bottom is acute, and the second top is obtuse. Can't be bothered to provide diagrams, though. Draw them yourself.

Any non-regular polygon from pentagon and up can have two or more right angles. Take a square and chop off the top and then make a two more connecting line segments (like a house with roof), and you have an irregular pentagon with 2 right angles at the bottom, for example.

No, trapezoids do not have right angles. A trapezoid is a quadrilateral with only one pair of parallel sides. The other two non-parallel sides can be of different lengths and angles.

It is a trapezoid in which the non-parallel sides are of the same length and subtend equal angles with the base. It can be viewed as an isosceles triangle whose apex has been removed by a line parallel to its base.

Set cube with front and back parallel and sides perpendicular to you. Cut diagonally though the flat top and bottom.

_\_________ .a\b _c\d________ .....\ When a line crosses 2 lines, 8 angles are formed. Four are exterior angles - outside the 2 lines, and four are interior angles. These are labelled a, b, c, d in the diagram. a & d are alternate interior angles because they alternate from one side of the intersecting line to the other; b & c are also alternate interior angles. They are also known as "Z-angles" because the top parallel line, the transversal and the bottom parallel line which define the two angles for the letter Z (or a distorted version of it). If angle a = angle d (in which case angle b = angle c as well), the 2 lines drawn horizontally are parallel. If alternate interior angles are equal, the 2 lines are parallel. OR If you know the lines are parallel, then alternate interior angles must be equal. Not the greatest diagram; please ignore the ... but even a lousy diagram helps. And no, you don't use lower case letters for angles but there shouldn't be any confusion.

A trapezium is a quadrilateral with two parellel sides which are not of equal length. If it is represented with its longest of the two parallel sides at the bottom, its two top angles are obtuse, or one is a right angle, and its two bottom angles are acute, though the one below a right angle would also be a right angle. The area of the trapezium is determined by multiplying the distance between the two parallel sides (called the height) by the average length of the two parallel sides.

An irregular Quadrilateral. It is like a rectangle with a piece cut off from one corner to the other side.www.mathsisfun.com/quadrilaterals.htmlTo expand a bit on the above:This describes a trapezoid which is a quadrilateral (four-sided figure) with only two sides parallel. In this case, the ends of the figure will be parallel, but one end will be longer than the other so that the top and bottom are convergent (non-parallel). The two upper angles will be 900 with one acute, and one obtuse angle at the bottom.
