Given: Oblique sketches of different shapes given.To do: To use isometric dot paper and make an isometric sketch for each one of the given shapes.Solution: Isometric sketches of given shapes are as below: 

Given: Nets and solids.To do: To match the nets with appropriate solids.Solution:

Given: Incomplete net for the cube.To do: To complete the net for the cube in two different ways.Solution:Here three faces of a cube are given. And we know that a cube has 6 faces. So we have to implement 3 more faces to make it a perfect cube in two ... Read More

Given: A net.To do: to check whether it can be net for a dice.Solution: We know that dice are a cube with dots on each face. The opposite faces have a total of 7 on a dice. So, the given net can't be a net for a dice, as its opposite ... Read More

Given: Angle of rotation:$(i).\ 45^{\circ}$?       $(ii).\ 17^{\circ}$?To do: To find that Can we have rotational symmetry of order more than 1 whose angle of rotation is:$(i).\ 45^{\circ}$?       $(ii).\ 17^{\circ}$?Solution:When an object is rotated in a particular direction, around a point, then it is known as rotational ...

Given: After rotating by $60^{\circ}$ about a center, a figure looks exactly the same as its original position.To do: To find the other angle at which will this happen for the figure.Solution: If a figure looks like the original figure at one angle, it will look like the original figure at all ... Read More

To do: To name the quadrilaterals which have both line and rotational symmetry of order more than 1.Solution:An imaginary line where we could fold the image and have both halves match exactly or where both the images are replicas of each other is said to be a ‘Line of Symmetry ... Read More

Rotational symmetryRotational symmetry is the property a shape has when it looks the same after some rotation by a partial turn. An object's degree of rotational symmetry is the number of distinct orientations in which it looks exactly the same for each rotationYes, when a figure has two or more ... Read More

To do: To name any two figures that have both line symmetry and rotational symmetry.Solution:Line of Symmetry: The ‘Line of Symmetry’ is the imaginary line where we can fold an image and have both halves matching exactly.Rotational symmetry:Rotational symmetry is the property a shape has when it looks the same after ... Read More

Given:Two nets to make dice (cubes).To do:To fill blank squares of the nets with appropriate numbers.Solution: Dice are cube-shaped solids having dots on each face. The number on the opposite faces should total to 7.In 1st diagram: First blank net is just opposite to the square numbered with 6. So we ... Read More
