Answer:
x² -4x +4
Step-by-step explanation:
(x-2)(x-2)
x²-2x -2x +4
x² -4x +4
Its the reflections over the Y and X axis. Then count how diagonal the line is
Answer:
Option (2) CPCTC
Step-by-step explanation:
In the given regular triangle ADF, all sides and angles of the triangle will be equal
∠A = ∠D = ∠F = 60°
And DE = EF [Since E is the midpoint of side DF]
Statements Reasons
1). ∠D ≅ ∠F Given
2). ∠DBE ≅ ∠ECF Given
3). DE ≅ EF Given
4). ΔDBE ≅ ΔECF By AAS property
Therefore, DB ≅ FC
Option (2) Corresponding parts of the congruent triangles are congruent (CPCTC)
