Question

1.BEandCE are two equal altitudes of a triangle ABC which congruence condition proves it to be isocles.

2.If AD is a altitude of an isosceles triangle and AD bisects BC, choose the congruence.

3.X is a point equidistant from two lines I and M interesting at point A. How can you say AX bisects the angle between them.

The option for three question are:
a)SAS
b)RHS
c)ASA
d)SSS​

Answer 1

Answer:

for the first part option (b) is correct.

for the second part option (a) is correct

for the third part first prove using RHS congruency and then angles are equal by CPCT rule.
