Which triangle is congruent to ∆ABC? What kind of triangles are they?
Hint
Use the angles and the sides to make sure they all match up in the correct order.
Answer
∆ABC ≅ ∆IHG, and both are acute isosceles triangles.
What congruence transformation should we perform on ∆ABC to see if it's congruent to the other triangle?
All the angles and sides are in order. We just have to shift it over.
Sliding the triangle over translates to translation.
Which triangle is congruent to ∆DEF? What kind of triangles are they?
Sometimes it might be difficult to tell whether a side has three or four tick marks, so be careful with that whole deal.
∆DEF ≅ ΔOMN, and both are acute scalene triangles.
What congruence transformation should we perform on ∆DEF to see if it's congruent to the other triangle?
Look at the relative locations of segments or angles.
We've gotta turn the triangle, meaning rotation.
