Agar koi mujhe iska answer step by step bataiyega to mai use follow thanks mark as brainlist karungi pakkka
Par step by step pleaseee​

Answer 1

Answer:

here is your answer

Step-by-step explanation:

5) i. in triangles abc and adc

ab is not equal to cd

bc is not equal to cd

ac is common to both the triangles

it doesn't full fill the conditions of RHS congruence.

thus, triangle abc is not congruent to triangle adc ( proved)

ii. in triangles abd and acd

ab is equal to ac

bd is equal to cd

ad is equal to ad ( common)

as it full fill the conditions of RHS

thus, triangle abd is congruent to triangle acd

I hope it will help you

Answer 2

Answer:

The two triangles shown in figure 2 are congruent to each other, by the RHS axiom.

Step-by-step explanation:

What is the RHS axiom? It is Right angle-side-Hypotenuse axiom.

Now, see my solution carefully. What I have shown is a property of any isosceles triangle. Here you will have to consider that the line AD is an altitude for the triangle ABC.

So, the hypotenuse for triangle ABD is AB, and that for triangle ACD is AC. Now, AB = AC as given in question.
