Question

. Given: c || d
3 is congruent to 4
Prove: 2 is congruent to 4

give statement and reasoning.

Answer 1

Answer:

1=2 vertically opposite angle

and 1=3 alternate angle

given : 3=4

• from this 2=3
• 2=4

Answer 2

Given:c//d

3 is congruent to 4

Or 3=4

To prove : 2 is congruent to 4

Or 2=4

Proof: 1=3(alternate interior angle) - (1)

1=2(vertically opposite angle)-(2)

From equation 1 and 2

2=3 - (3)

3=4(given)-(4)

From equation 3 and 4

2=4 hence proved
