Congruent Triangles

Given the picture, name the congruent triangles.

•  $\Delta CIE\ \&\ \Delta NSW$ 

•  $\Delta CIE\ \&\ \Delta SWN$ 

•  $\Delta IEC\ \&\ \ \Delta WSN$ 

•  $\Delta ECI\ \&\ \Delta NSW$ 

Given the picture, choose the best statement that describe the two triangle cones.

• they have the same shape

• they have the size

• they are congruent

• they are not congruent
