NCERT Solutions for CBSE Class 9 Maths

Some of the sample questions from CBSE Class 9 Mathematics Solved Practice Paper : Set-I are given below:

Q. If the vertical angle of an isosceles triangle is 100o then find the measures of its base angles.

Sol.

Let the measure of each of the base angles be x°.
Now,

x + x + 100 = 180o                   [ Angle sum property of a triangle]

⇒         2x + 100 = 180

⇒         2x = 180 – 100 = 80

⇒          x = 40
∴ The measure of each of the base angles of the triangle is 40°.

Q. A batsman in his 11th innings makes a score of 68 runs and there by increases his average score by 2. What is his average score after the 11 th innings.

Sol.

Let average score after 11th innings = x

Then average after 10th innings = x – 2

According to question,

10(x – 2) + 68 = 11x

⇒        10x – 20 + 68 = 11x

⇒        x = 48

Hence, the average score after 11th innings is 48.

Q. AB is a line segment and P is its mid-point. D and E are points on the same side of AB such that ∠BAD = ∠ABE and ∠EPA = ∠DPB. Show that Show that

(i) ΔDAP ≅ ΔEBP

Sol.

As ∠ EPA = ∠ DPB                  (Given)

⇒ ∠ EPA + ∠DPE = ∠ DPB + ∠DPE

∴  ∠APD = ∠BPE                      …(i)

Now in ΔDAP and ΔEBP

AP = BP                                  (Given P is midpoint of AB)

∠APD = ∠BPE                          (From equation (i))

Hence ΔDAP ≅ ΔEBP (By ASA congruence rule)
