State whether the statements are True or False.

Sum of two sides of a triangle is greater than or equal to the third side.

Fill in the blanks to make the statements true.

In Fig. 6.27,

(i) ∠TPQ = ∠____PQR____ + ∠____PRQ____

(ii) ∠UQR = ∠____QPR____ + ∠____PRQ____

(iii) ∠PRS = ∠____RPQ____ + ∠____PQR____

State whether the statements are True or False.

In a triangle, sum of squares of two sides is equal to the square of the third side.

State whether the statements are True or False.

The difference between the lengths of any two sides of a triangle is smaller than the length of third side.

State whether the statements are True or False.

In ∆ABC, AB = 3.5 cm, AC = 5 cm, BC = 6 cm and in ∆PQR, PR = 3.5 cm, PQ = 5 cm, RQ = 6 cm. Then ∆ABC ≅ ∆PQR.
