Isosceles trapezoids have 2 (occasionally 3) equal sides and have 2 pairs of equal angles, but that's not case if they're not isosceles.

It doesn't have to, but it can. A trapezoid is any shape in which there is a pair of parallel sides. This means that a square can be classified as a trapezoid. But notice that a four-sided shape can never have ONLY three 90° angles. The sum of angles of a four-sided shape is 360--this means that if you have three 90° angles, then the remaining angle must be 360-3(90) which is 90°, giving you four right angles. * * * * * No you cannot. As indicated in the second paragraph of the above answer, three right angles implies that all four angles are right angles and that makes the figure a rectangle (or a square).

A pentagon with 3 right angles is considered to be an irregular pentagon because not all angles and all sides are equal.

A hexagon can be broken into any number, k (â‰¥3) of trapezoids, and these will have 4k angles.

If a diamond does not necessarily have to have right angles in it, but if it does then all four corners have to be right angles. Think of a diamond as a turned square or rhombus.

No, not with two right angles. All the angles in a triangle add up to 180, you have that in two angles.

There are 3 obtuse angles. All 3 exterior angles are obtuse. (This is, admittedly, a bit of trick question!)

A right angle triangle has 3 sides and 3 inside angles of 90 degrees and two acute angles that add up to 90 degrees and all 3 angles add up to 180 degrees.

An equilateral triangle, has 3 equal sides and 3 equal angles. However, in a regular equilateral triangles, none of these angles are right angles (90 degrees), they are all 60 degrees.

Extend all the lines of a right-angled triangle with sides of 3, 4 and 5 units. The extension of the lines forming the right angle will produce 3 other right angles. The extension of the lines forming the other two angles will produce 6 other angles. This gives a total of 12 angles, 4 of which are acute, 4 right and 4 obtuse.
