Answer:
5. B, C and E
6. C
7. None
8. A and D
9. F and G
Step-by-step explanation:
See attachment for complete question
5. B, C and E
B, C and E are not parallelogram because they do not have 2 pairs of parallel sides
B and E are trapeziums while C is just a quadrilateral.
6. C
In (5) above, we established that B and E are trapeziums while C is not. This implies that only C is a quadrilateral.
7. None
A square is a parallelogram. So, it is not possible for a shape to be a square and not be a parallelogram.
8. A and D
A is a rhombus. D is a square and will be treated as a rhombus because all sides are equal.
9. F and G
These shapes have 2 pairs of parallel lines but all 4 sides are not equal; only the opposite sides are equal.
 
        
             
        
        
        
Step-by-step explanation:
Here with reference angle 45°
Hypotenuse ( h) = y
Perpendicular (p) = x
base (b) = 5√2
We know 
tan 45° = p/b
1 = x / 5√2
Therefore x = 5√2
Now 
h = √(5√2)^2 + 5√2)^2
 = √ 50 +50
 = √100
 = 10

Answer:
The statement is false
Step-by-step explanation:
we know that 
if the triangle is a right triangle
then
the triangle must satisfy the Pythagoras Theorem

we have



substitute



therefore
Is not a right triangle
The statement is false
