Question

Pls answer 9, 10 and 11 with explanation

Answer 1

Answer:

9th question

angle Q = angle M= 90° given

PQ=PM given

PR = PR commom

According to RHS CONGRUENCE

TRIANGLE PQR CONGRUENT TO TRIANGLE PMR

QM = MR (C.P.C.T)

HENCE PROVED.

10th question.

AB = AC( GIVEN)

D is the mid point so that it bisects BC therefore

BD=DC

AD =AD (COMMON)

ACCORDING TO SSS CRITERION

TRIANGLE ABD CONGRUENT TO TRIANGLE ACD.

HENCE PROVED.

11TH QUESTION.

ANGLE DAB =ANGLE DAC

AD=AD(COMMON)

ANGLE C = ANGLE B ( perpendicular)

ACCORDING TO ASA CONGRUENCE

TRIANGLE ABD CONGRUENT TO TRIANGLE ACD.

HENCE PROVED.

HOPE IT HELPS YOU....

THANKYOU.......
