Question

choose right option
1. In a right triangle ca+b', the hypotenuse will be ________
2. The angles of a triangle are in the ratio 2: 3:4. What is the measure of the smallest angle? _______
3 In APOR, S is the mid-point of QR, then PS will be ________
4.If all the three angles of a triangle are equal, then the measure of each angle is _______
5.Which of the following triplets cannot be the angles of a triangle? _______​

Answer 1

Given that:

QP=8cm,PR=6cm and SR=3cm

(I) In △PQR and △SPR

∠PRQ=∠SRP (Common angle)

∠QPR=∠PSR (Given that)

∠PQR=∠PSR (Properties of triangle )

∴△PQR∼△SPR (By AAA)

(II)

SP

PQ

=

PR

QR

=

SR

PR

(Properties of similar triangles)

⇒

SP

8cm

=

3cm

6cm

⇒SP=4cm and

⇒

6cm

QR

=

3cm

6cm

⇒QR=12cm

(III)
