What is the shape of the 6 sided shape?
Six sided shapes are called hexagons. If all 6 sides are the same size, then the shape is called a regular hexagon.
What shapes can you make using hexagons?
The answer will depend on whether the hexagons are all the same size or not, whether they come together in a plane or 3-dimensions, whether they can join at vertices or only sides. Two hexagons, of the same size, that are coplanar can make a concave hendecagon (meet at side) or a concave dodecagon (meet at vertex). Two concave hexagons can also join (dovetail) to make one hexagon. The question is under-specified.
How can you show that all sides and angles of a hexagon are congruent without using a ruler or a protractor?
You can do that by simply proving that the hexagon is a regular hexagon. You could do this by dividing the hexagon into 6 equilateral triangles of the same size successfully that tesselate to form a hexagon, thus proving that all sides are equal.
Are all corresponding sides of similar hexagons always congruent?
No. They are proportional, meaning that if side A of one hexagon is, for example, twice the corresponding side A' of the other hexagon, then side B will also be twice the size of side B', etc.
Are no hexagons are congruent?
Nope. They can be any shape or size meaning they CAN be congruent.
Is a house-shaped pentagon a regular pentagon?
No. A regular polygon has all sides the same length and all angles the same size. A regular pentagon has 5 angles each 108 degrees. A house-shaped pentagon does not have all angles the same size, so therefore it cannot be regular.
What do lab puppies and regular puppies have in common?
Lab puppies and regular puppies are practically the same in many respects. Although size of diet may depend on size of the animal, the constituent parts of meals will be the same. They require the same care and regular walks.
Why isn't a pentagon a regular shape?
Regular just means all the angles are the same size. A pentagon can be regular but it need not be.
Are full and standed the same size?
Full, standard and regular are common names for the same size mattress. 53" x 54".
Is a marsh rabbit bigger than a regular rabbit?
no its the same size
When midgets poop is it the same size as regular people poop?
