Can two shapes be congruent and not similar?
In short, no. Similar shapes are shapes in which all corresponding angles congruent regardless of the length of the sides. Congruent shapes have congruent corresponding angles and corresponding sides. In effect congruent shapes is a special condition of similar shapes.
Do any 2D shapes have no straight sides but have right angles?
No
What shape does triangles make?
Triangles can make various shapes depending on their sides and angles. Some common shapes formed by triangles include equilateral triangles (with three equal sides), isosceles triangles (with two equal sides), scalene triangles (with no equal sides), and right triangles (with one 90-degree angle).
What are 3 attributes of a quadrilateral?
It has 4 sides Its 4 interior angles add up to 360 degrees It can have different shapes.
What are similarities of congruent shapes and similar shapes?
The angles for congruent shapes and the angles in similar shapes are all the same. All the sides are also proportional in both. Basically, all congruent shapes are similar but not all similar shapes are congruent.
Are regular shapes shapes with all the same angles and sides?
Yeah.
What shape has 3 right angles and more than 4 sides?
definitely a pentagon can.. It can be any shapes that have more than 4 sides except that they can't be regular shapes.
Can two shapes be congruent and not similar?
In short, no. Similar shapes are shapes in which all corresponding angles congruent regardless of the length of the sides. Congruent shapes have congruent corresponding angles and corresponding sides. In effect congruent shapes is a special condition of similar shapes.
Examples of regular shapes?
Regular shapes are shapes where all the sides and angles are equal. One example of a regular shape is a square because all the sides are the same and all the angles are 90 degrees.
When two shapes are similar does that mean they have the same amount of sides?
No, it means they have either 2 sides and 1 angle congruent, 2 angles congruent, 2 angles and a side congruent, or 3 sides congruent.
How are regular and irregular shapes the same?
Regular shapes:all sides and angles are the same Irregular shapes: different angle and sides
What has no congruent sides and no congruent angles?
Irregular polygons, curves, open shapes all lack congruence of angles and sides.
What are called shapes having many sides and angles?
Polygons
Do any 2D shapes have no straight sides but have right angles?
No
What shape does triangles make?
Triangles can make various shapes depending on their sides and angles. Some common shapes formed by triangles include equilateral triangles (with three equal sides), isosceles triangles (with two equal sides), scalene triangles (with no equal sides), and right triangles (with one 90-degree angle).
How many angles does a hexagon have?
A 6 sided hexagon has 6 angles that add up to 720 degrees
Characteristics of two dimensional shapes?
It all depends on the shape; different 2D geometrical shapes have different characteristics.Some specialized geometrical shapes:Square: 4 sides; 4 equal sides; 2 pairs of parallel sides; 4 right angles (90 degrees)* A square is a rectangle.Rectangle: 4 sides; 2 pairs of parallel sides; 4 right angles (90 degrees)* A rectangle is not a square.Triangle (equilateral): 3 sides; 3 equal sides; all angles 60 degreesTriangle (isosceles): 3 sides; 2 equal sides (usually the base is the odd one)Triangle (scalene): 3 sides; all uneven sides and anglesRhombus: 4 sides; 4 equal sides; 2 pairs of parallel sides; 4 equal anglesParallelogram: 4 sides; 1 pair of parallel sidesThese are the basic geometrical 2D shapes, but there are others that are more complex.
