Answer:
400 ml
Step-by-step explanation:
1 litre = 1000 ml
1000 ml = 1 litre
Answer:
Option (2) CPCTC
Step-by-step explanation:
In the given regular triangle ADF, all sides and angles of the triangle will be equal
∠A = ∠D = ∠F = 60°
And DE = EF [Since E is the midpoint of side DF]
Statements Reasons
1). ∠D ≅ ∠F Given
2). ∠DBE ≅ ∠ECF Given
3). DE ≅ EF Given
4). ΔDBE ≅ ΔECF By AAS property
Therefore, DB ≅ FC
Option (2) Corresponding parts of the congruent triangles are congruent (CPCTC)
C!
parallel line: m1 x m2 = -1
-3 x 1/3 = -1
Answer:
No
Step-by-step explanation:
By using the Pythagoras theorem, it can be easily determined that whether the triangle is right triangle or not.
Thus, where where a and b are the legs and c is the hypotenuse.
Let a=6ft, b=21ft and c=23ft, then
which is not possible, therefore the given triangle is not right triangle because it does not satisfy the Pythagoras theorem.
