Answer:
Question 6
There is not enough information to determine congruency
Question 9
yes; The triangles are congruent by hypotenuse-leg congruence
Step-by-step explanation:
* Lets revise the cases of congruence Â
- SSS  ⇒ 3 sides in the 1st Δ ≅ 3 sides in the 2nd Δ
- SAS ⇒ 2 sides and including angle in the 1st Δ ≅ 2 sides and Â
 including angle in the 2nd Δ Â
- ASA ⇒ 2 angles and the side whose joining them in the 1st Δ Â
 ≅ 2 angles and the side whose joining them in the 2nd Δ
- AAS ⇒ 2 angles and one side in the first triangle ≅ 2 angles Â
 and one side in the 2ndΔ
- HL ⇒ hypotenuse - leg of the first right angle triangle ≅ hypotenuse
 - leg of the 2nd right angle Δ
- HA ⇒ hypotenuse - angle of the first right angle triangle ≅ hypotenuse
 - angle of the 2nd right angle Δ
- LL ⇒ leg - leg of the first right angle triangle ≅ leg - leg of the
 2nd right angle Δ
* Now lets solve the problem
# Question 6
- There are two right angle triangles
- They have two different legs
- There is no mention abut legs equal each other
- There is no mention about hypotenuses equal each other
- There is no mention about acute angels equal each other
∴ There is not enough information to determine congruency
# Question 9
- There are two right angle triangles
- Their hypotenuse is common
- There are two corresponding legs are equal
∵ The hypotenuse is a common in the two right triangles
∵ Two corresponding legs are equal
- By using hypotenuse-leg congruence
∴ yes; The triangles are congruent by hypotenuse-leg congruence
