Question 1 of 10
1. Question
The length of each side of a rhombus is 10cm and one of its diagonal is of length 16cm. The Length of the other Diagonal is:
Correct
Firstly we know that diagonal of rhombus bisects each other. thus half of diagonal =8cm.
by pythagoras theorem we find another half of diagonal.that is 6 cm
as we diagonals bisect other thus another diagonal
=2×6=12cm

7. Question
Given a triangular prism, then what can we conclude about the lateral faces?
Correct
In a triangular prism, the bases are triangles and the lateral faces are parallelograms.
Thus it can be both rectangles and parallelograms.
So, option (2) is correct.
If the faces are rectangles, then we call it as right triangular prism
Observe the following figure.
It is clear that the faces of the above figure are rectangles and hence it is right triangular prism.

Question 10 of 10
10. Question
Angles of a quadrilateral are in the ratio 3 : 6 : 8: 13. The largest angle is :
Correct
3p + 6p + 8p + 13p = 30p = 360° ⇒ p
= 12° Largest angle is 13p = 13 × 12°
= 156°
Incorrect
3p + 6p + 8p + 13p = 30p = 360° ⇒ p
= 12° Largest angle is 13p = 13 × 12°
= 156°
