QUESTION: 1

### In the given fig, P and Q are points on the sides AB and AC respectively of Δ ABC such that AP = 3.5 cm, PB = 7 cm, AQ = 3 cm and QC = 6 cm. If PQ = 4.5 cm, find BC.

Solution:

Therefore, by converse of Basic Proportionality Theorem, we have QP || CB
Hence, ∆AQP ~ ∆ACB [Using AA similar condition]

∴
⇒
⇒

QUESTION: 2

Solution:
QUESTION: 3

### ΔABC ~ ΔPQR, ∠B = 50° and ∠C = 70° then ∠P is equal to​

Solution:

Similar triangles have corresponding angles equal. So Angle Q=Angle B = 50° and Angle R = Angle C = 70° . So by angle sum property, Angle P+Angle Q +Angle R = 180°
Angle P=180° - 50° - 70° = 60°

QUESTION: 4

Two congruent triangles are actually similar triangles with the ratio of corresponding sides as.​

Solution:
QUESTION: 5

Which geometric figures are always similar?​

Solution:

It can be found that circles map one  onto another.So they are similar figures. A regular polygon is a polygon which has the same sides and equal measures of angles. So they are also similar.
