A triangle.
Depending on the definition that is used, a trapezium is either a figure with four sides that has no parallel sides (American) or a figure with fours sides that has two parallel sides (British). Either way, a trapezium can not have 3 right angles.
if the angles of a figure are the same but the sides aren't, it is similiar. Congruent is angles and sides exactly the same
A pentagon has five sides and five angles.
Any triangle that is not a right angle triangle
A triangle.
A triangle has 3 sides and 3 interior angles that add up to 180 degrees.

Any triangle that is not a right angle triangle
a circle
A square, rectangle, or quadrilateral
All triangles have exactly 3 sides. That is what the word triangle means, a geometrical figure having 3 angles and 3 sides. Always 3.
-- it's a closed, plane figure -- it has 3 sides, 3 vertices, 3 interior angles (any one of these 3 statements implies the other 2) -- the sum of its interior angles is 180 degrees
The 3 names for this figure are: 1. Square - all sides are parallel, there are 4 right angles, and all the sides are the same length. All squares are quadrilaterals and parallelograms. 2. Quadrilateral - 4 sides. NOT all quadrilaterals are squares, however. 3. Parallelogram - all sides are parallel. NOT all parallelograms are squares, however.
A hexagon has six sides and six angles.
