Question

please answer..........

Answer 1

in triangles ABE AND TRIANGLE ACF
ANGLE AFC = ANGLE ABF(EACH 90) DEGREE
BE=CF(GIVEN)
& ANGLE A IS COMMON
THEREFORE TRIANGLE ABE IS CONGRUENT TO TRIANGLE ACF.
BY AAS RULE.
SO AB=AC (BY CPCT)
2. AB=AC BY (CPCT )
=> ABC IS AN ISOSCELES TRIANGLE

Answer 2

BE=CF

<BAE=<CAB

<BAE=<CAF

REASON

given side

common side

each 90 degree

AB=AC ( BY CPCT)
