Degrees in a parallelogram?
All four sided shapes in 2-d have 360 degrees when you sum all the internal angles
How much degrees is a pentagon?
The sum of internal angles of a shape is given by the equation 180(n-2) where n is the number of sides. For a pentagon, which has 5 sides, this would be 180x3 = 540. The sum of external angles of a shape is given by (180-(x/n))n where n is the number of sides and x is the sum of internal angles. For a pentagon, this would be 5x(180-540/5) = 360
The probability of guessing and getting this question right is 1 out of 2. True of False?
True. When there are only two answers, so guessing should give you a 50% or 1 out of 2 chance of getting the right answer.
How many edges corners and faces does a cylinder have?
2 edges (curved), 0 corners, and 3 faces (one of which is not flat) ------------------------------------------------------------------------------------------------- A cylinder has 0 vertices (corners), 0 edges, and 2 faces. If you need convincing, my proof is Euler's formula, which which relates all three and is true for all solids in Euclidean 3-space: V + F - E = 2 0 + 2 - 0 = 2 You cannot consider the curved boundaries when counting faces or edges.
Why do only the triangle hexagon and square tile?
It's not because of a natural law or something; it's inherent in the structure of space, and the shapes of triangles, hexagons, and squares. Your question is like asking, "why does 2 + 2 = 4?" There's not a reason, they just do because that's how things are.Also, they aren't the only shapes that tile, just the only regular polygons that tile.>>M.T.
What has 5 vertices 2 of which are right angles?
An irregular 5 sided pentagon can be constructed including two right angles.
What shapes have 2 equal angles?
a right angled triangle.
What is a shape with 4 sides 4 vertices and exactly 2 right angles?
Square
What shape has 4 right angles 2 pairs of equal angles and only 2 right angles?
That's three different shapes: a rectangle, a rhombus and a trapezoid respectively.
Which property is common to all quadrilaterals?
Quadrilaterals are plane (2-D) shapes. They are bounded by four straight sides. They have four vertices and the sum of the internal angles at these vertices add to 360 degrees.
What are the parts of a rectangle?
4 sides 4 right angles 2 diagonals 4 vertices
Which 2 shapes have the same edges vertices and faces?
Congruent shapes.
What 2 shapes have 4 right angles and 2 pairs of parallel sides?
a square and a rectangle
What are two ways a rectangle and a square are alike?
Both have 2 pairs of opposite parallel sidesBoth have 4 interior right angles
What has 2 right angles and 2 parallel lines?
A square or rectangle are the only regular polygons, but many other shapes have two right angles and two parallel lines.
WHAT SHAPE has 2right angles?
The simplest shape that can have 2 right angles is a rectangle or a square. You can make an unlimited number of more complex shapes, though. A house shape is a pentagon with 2 right angles--you could even make it with 3 right angles.
2 solid shapes together the shapes have 8 faces 12 edges and 8 vertices one of the shapes is a rectangular prism what is the second shape?
2 solid shapes together have 8 faces, 12 edges 8 vertices
