the shape of the following things are (a) Your instrument box- Cuboid (b) A brick- Cuboid (c) A matchbox-Cuboid (d) A road-roller- Cylinder (e) A sweet laddu-Sphere
In a square pyramid, the number of Faces =           (Four triangular faces and one square face) Edges =           (Four edges of the square base and other four joining at the top)    Corners = 
(a) a scalene acute angled triangle. :  Scalene : All side of different length Acute angled : All angles less than    (b) an obtuse angled isosceles triangle Isosceles traingle: Only two sides are of equal length Obtuse angled : At least one angle greater than 
No, the angle is not more than than 1 right angle.  For each hour, angle made =  Therefore, when the hour hand moves from 5 to 7, the angle made = 
Yes, the revolution of the hour hand is more than 1 right angle. For each hour, angle made =  Therefore, when the hour hand moves from 12 to 5, the angle made = 
(a) One fourth revolution: From (b) Half revolution: From (c) Three fourth revolution: From (d) Three fourth revolution: From (e) Half fourth revolution: From  
One-fourth revolution =  The angle name for one-fourth revolution is "Right Angle"
Half a revolution =  The angle name for half a revolution is "Straight Angle".

We have made the regular octagon ABCDEFGH and by joining vertices H, C, D and G we have formed the rectangle HCDG
We have drawn the regular Hexagon ABCDEF and by joining the vertices B, D and F we have formed the Equilateral Triangle BDF.
(a) The given figure is not a polygon as it is not a closed figure. (b) The given figure is  a polygon. (c) The given figure is not a polygon as a polygon is enclosed only by line segments. (d) The given figure is not a polygon as a polygon is enclosed only by line segments.
Square is the only quadrilateral with sides equal in length and angles equal in measure, therefore, a square is the regular quadrilateral.
