From C you draw a parallel to AB. From left to right name the angles:
C₁, C₃ and C₂
∠C₁ = ∠A₁ (interior alternate)
∠C₃ = ∠C₃
∠C₂ = ∠B₂ (interior alternate), but ∠C₁ + ∠C₃ + ∠C₂ = 180° (straight line),
Then: ∠A₁ + ∠C₃ + ∠B₂ = 180°
Answer:
Step-by-step explanation:
After reflection about y-axis, A'B'C' must be translated down 6 units to create image DEF.
ABC and DEF are congruent due to the following common properties of reflections and translations.
1. does not change the nature of geometric elements, i.e. maps a line to a line, a segment to a segment, etc.
2. preserve lenths of segments.
3. preserves angles
By the congruent theorem of SSS, the two triangles are congruent.
