Question

Pls do question 6 and 7

Answer 1

Answer:

Q6  BA=AD(2.5 cm each )

      BC=CD(5 cm each)

      AC=AC(Common)

by sss congruency

triangle ABC is congruent to ABC

Q7 ABT

Answer 2

Answer:

Here's your answer mate

Firstly and the main work you have to do is look at them very consciously.

To prove the Triangle congruent You have 3 rules:-

1. SAS
2. AAS
3. ASA

Que-6

Given= AB- 2.5cm, BC- 5cm, AD- 2.5cm and DC- 5cm

To Prove= ∆ABC ~ ∆ADC

∆ABC and ∆ADC

AB = AD (given)

<A = <A (common)

BC = DC (given)

These two triangles are now congruent by SAS congruency rule.

Que-7

∆ABC= ∆ABT
