Step 1 : Choose ONE of the following triangles complete the table below:
1. Obtuse Scalene Triangle Translation to prove SSS Congruence
or
2. Isosceles Right Triangle Reflection to prove ASA Congruence
or
3. Equilateral Equiangular Triangle Rotation to prove SAS Congruence

A (1, 4) (x,y) -> (x+ ,y -) A’ ( , )
B ( 7,4) (x,y) -> (x+ ,y - ) B’ ( , )
C (8,9) (x,y) -> (x+ ,y -) C’ ( , )
The appropriate table is also shown below.
The triangles ABC and A'B'C' are congruent by SSS through Obtuse Scalene Triangle Translation because the corresponding sides are congruent
Two triangles are congruent if their size and shape are the same.
Now we have to transform the triangle,
The coordinates of the triangle ΔABC are given as:
A = (1, 4)
B = (7,4)
C = (8,9)
so the lengths of the sides of the triangle are given by
AB= √(7-1)²+(4-4)²= √6²= 6
BC= √(8-7)²+(9-4)²= √1²+5²= √1+25= √26
CA= √(8-1)²+(9-4)²= √7²+5²= √49+25= √74
In order to prove the SSS congruence, we have to transform the triangles under the following translation rule:
(x,y) -> (x -3, y +6)
in the above translation,
The triangle will be translated 3 units left
And then translated 6 units up.
So, we have the new coordination of the points of the translated triangle ΔA'B'C'
A' = (1-3, 4+6)
A' = (-2, 10)
B' = (7-3, 4+6)
B' = (4, 10)
C' = (8-3, 9+6)
C' = (5, 15)
Now
so the lengths of the sides of the triangle are given by
A'B'= √(4-(-2))²+(10-10)²= √6²= 6
B'C'= √(5-4)²+(15-10)²= √1²+5²= √1+25= √26
C'A'= √(-2-5)²+(10-15)²= √(-7)²+(-5)²= √49+25= √74
By comparing two triangles ΔABC and ΔA'B'C'
AB ≅ A'B'
BC ≅ B'C'
CA ≅ C'A'
Hence ΔABC ≅ A'B'C' (By S-S-S rule)
By the above transformation, the triangles ABC and A'B'C' are congruent by SSS because the corresponding sides are congruent as all the points are gone through the same transformation.

Answer:
In case (a) car makes 105° turn.
In case (b) car makes 75° turn.
In case (c) car makes 105° turn.
Step-by-step explanation:
Figure is redrawn To explain properly (in attachment)
Given : streets are parallel means ║
,
AB - 4th street , CD - 3rd street and XY - King Ave.
∠XLA = 75°
To find : (a) ∠XLB
(b) ∠LMD (left onto 3rd streat means left of car)
(c) ∠YMD (right means right side of car)
∠XLB + ∠XLA = 180° (Linear Pair = 2 adjacent angles are
supplementary)
∠XLB + 75° = 180°
∠XLB = 180 - 75
∠XLB = 105°
∴ In case (a) car makes 105° turn.
∠LMD = ∠XLA = 75° (Corresponding angles of parallel lines are equal)
∠LMD = 75°
∴ In case (b) car makes 75° turn.
∠YMD + ∠LMD = 180° (Linear Pair = 2 adjacent angles are
supplementary)
∠YMD + 75° = 180°
∠YMD = 180 - 75
∠YMD = 105°
∴In case (c) car makes 105° turn.
