Fill in the blanks:
(i) Data means information in the form of _P __.
(ii) Data obtained in the _Q __form is called row data.
(iii) The number of times a particular observation occurs is called its _R __.
(iv) Arranging the numeral figures in an ascending or descending order is called an/a _S __.
In ΔDEF and ΔPQR, DE = DF, ∠F = ∠P and ∠E = ∠Q. The two triangles are
A Isosceles but not necessarily congruent
B Isosceles and congruent
C Congruent but not isosceles
D Neither congruent nor isosceles
The answer should be (B). It is because if angleE = angleQ and angleF = angleP, then angleD = angleR so the triangles are similar. Also, we can see that angleE = angleQ and angleF = angleP, so DE = QR and DF = PR, but DE=DF, so QR=PR and hence both triangles are both congruent and isosceles.
A pole is painted red and white. The red portion is 1.8 m long and the white portion is three times as long as the red portion. How long is the pole?
A 5.4 m
B 7.2 m
C 3.6 m
D None of these
After I searched this question on google ,the site get practice it said the answer is C -3.6
