A triangle.
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
Any triangle that is not a right angle triangle
A pentagon has five sides and five angles.
A triangle.
A triangle has 3 sides and 3 interior angles that add up to 180 degrees.

Like all triangles an Isosceles triangle has three sides and three angles. However, in an Isosceles triangle , two of the three sides are the SAME length. Also in an Isosceles triangle, two of the angles of the three have the same degree value. Here are the names of different type of triangle. EQUILATERAL ; All sides the same length , all angles at 60 degrees. ISOSCELES ; As above RIGHT-ANGLED(90 DEGREE) One angle MUST be 90 degrees. SCALENE ; All three sides of different lengths and all three angles of different degree values. In all CASES the sum of the interior angles is ALWAYS 180 degrees.
-- 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
A square, rectangle, or quadrilateral
a circle
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 figure with twice as many sides as a triangle is a hexagon. A triangle has 3 sides, so double that would be 6 sides. A hexagon is a polygon with 6 sides and 6 angles. It is a regular polygon with all sides and angles congruent.
