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.
A test consists of 10 truefalse questions To pass the test a student must answer at least 7 questions correctly on a true-false exam what is the probability that he or she get them all right?
The probability of getting all 10 questions right is, P(10) =(1/2)10 =0.0009765...9 questions right, P(9) =10C9 ∙(1/2)10 =10∙(1/2)10 ~ 0.009765...8 questions right, P(8) =10C8 ∙(1/2)10 ~ 45∙(1/2)10 ~ 0.043945...7 questions right, P(7) =10C7 ∙(1/2)10 ~ 120∙(1/2)10 ~ 0.1171875...The probability of passing the test with any of the grade is the sum of all theabove; P(passing)~ 0.1719 ~ 17.2%
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.
What are the parts of a rectangle?
4 sides 4 right angles 2 diagonals 4 vertices
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 2 shapes have 4 right angles and 2 pairs of parallel sides?
a square and a rectangle
Which 2 shapes have the same edges vertices and faces?
Congruent shapes.
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.
Do 2-dimensional shapes have vertices?
Yes, 2-dimensional shapes have vertices, which are the points where two or more edges meet. For example, a triangle has three vertices, while a square has four. The number of vertices varies depending on the type of polygon; for instance, a pentagon has five vertices.
WHAT SHAPE has 2right angles?
A rectangle has two right angles. In a rectangle, opposite sides are equal in length and all interior angles are 90 degrees. This geometric property distinguishes a rectangle from other shapes, such as squares or parallelograms, which may also have right angles but do not necessarily have exactly two right angles.
