Answer:
Ans 1. 
Ans 2.a.

Ans.2.b.

Step-by-step explanation:
Solution:
1.
Vertically opposite angles are equal.

2.a.
proof for Δ BAC ≅ ΔKJL by SAS postulate.
InΔ BAC and Δ KJL
BA ≅ KJ Given
∠ BAC ≅ ∠ KJL {measure each angle is 90}

2.b.
proof for Δ BAC ≅ ΔKJL by HL theorem.
InΔ BAC and Δ KJL
BA ≅ KJ Given
∠ BAC ≅ ∠ KJL {measure each angle is 90}

Answer:
40
Step-by-step explanation:
5 / 8 = x / 64
5 / 8 x 64 = x / 64 x 64
5 x 8 = x
40 = x
I hope this helps :)
Answer:
These triangles cannot be proved congruent
Step-by-step explanation:
The theorems for congruence are SSS SAS ASA AAS. Here, there is only one common side and one common angle marked, therefore you cannot prove congruency.
